New TrickMo Variants Exploit Fake Lock Screens to Steal Android PINs

 



A perilous new variant of the Android banking malware TrickMo has been discovered, capable of mimicking the Android lock screen and stealing users' PINs. This comes according to the data compiled by the security firm Zimperium, who made a deep analysis of the malware. The firm said that some 40 new variants of TrickMo have been found in the wild. These are associated with 16 dropper applications and 22 different command and control (C2) servers.

The new report follows earlier research by Cleafy, which had already managed to detect some of these, but not all, variants. TrickMo had been observed used in cyberattacks since September 2019, although it wasn't documented until last year by the IBM X-Force group.


How TrickMo Works to Deceive

One such feature in this new version of TrickMo is the fake Android lock screen designed to further dupe the users into handing over their PIN or unlock pattern. The screen seems like a real one. It actually renders in full-screen mode to mimic the prompt from an original Android. Once the user inputs his credentials, malware will capture that and transmit over to a remote server along with its unique identifier. This will provide thieves with access to the device later, often when it is not actively monitored, allowing them to go on and carry out whatever fraudulent activities they want.

In addition, TrickMo has other malicious abilities-the intercepting of one-time passwords, screen recording, exfiltration of data, and even the remote control of the infected device. Thus, TrickMo is another banking trojan, which mainly operates relying on the stealing of login credentials with the presentation of phishing pages of various banks.


The New Generation of Adaptation Malware

New variants of TrickMo malware attempt to exploit the Accessibility Service permission in Android. As a result, the malware would be able to grab greater control over the device and the possibility of automating different actions without even letting the actual user know about such actions. This is an abuse of accessibility features that grants the malware easier ways for interacting with system prompts, such as giving itself further permissions or making phishing pages appear.

Cyber security experts consider the mature and dynamic capabilities to make TrickMo a most dangerous threat. The phishing screens will be more likely to capture the users, and once the credentials are captured, then hackers can carry out unauthorised transactions using their banking apps or log in to other sensitive accounts.


Large-scale Impact on Victims

Zimperium's research showed that at least 13,000 victims from several countries, such as Canada, United Arab Emirates, Turkey, and Germany, have been affected by the TrickMo malware. The real number of attached devices, however, may be much higher as the malware operates through multiple C2 servers.

It targeted most of the banking applications but has since grown to target many more applications such as VPN services, streaming services, online e-commerce websites, and even social media and enterprise-based platforms. More alarming, it threatens because it can compromise user accounts associated with different kinds of services, not just financial services.


Staying Safe from TrickMo

This spreads through misleading the users into downloading the malicious APK files from unknown sources. To avoid infection, users are not encouraged to click on any links whatsoever-those coming through SMS or direct messages from unknown contacts in particular. Enablement of Google Play Protect is likely to prevent known variants of TrickMo from being installed on Android devices.

The sophistication level of malware like TrickMo tends to keep reminding everyone of the importance of maintaining their software up to date and not to interact with any unfamiliar apps or websites. As it continues to morph into even dangerous forms, cybersecurity experts have kept alerting Android users to be on high alert and ensure that such security features like Google Play Protect are turned on in order to provide a first line of defence against such threats.

Zimperium has taken the noble step in releasing TrickMo's C2 infrastructure details on GitHub, thus being in a better position to help cybersecurity experts and organisations ward off the trojan. It is important to note that while saying so, users are advised to be vigilant and take proper measures to ensure their sensitive information will not be compromised by malicious software such as TrickMo.


TrickMo Banking Trojan Unveils Advanced Threat Capabilities in Latest Variant

Malware Analyst at Zimperium, Aazim Yaswant, has released an in-depth report on the most recent TrickMo samples, highlighting worrisome new functionalities of this banking trojan. Initially reported by Cleafy in September, this new version of TrickMo employs various techniques to avoid detection and scrutiny, such as obfuscation and manipulating zip files. 

Yaswant’s team discovered 40 variants of TrickMo, consisting of 16 droppers and 22 active Command and Control (C2) servers, many of which remain hidden from the broader cybersecurity community.

Although TrickMo primarily focuses on stealing banking credentials, Yaswant's analysis has exposed more sophisticated abilities. "These features allow the malware to access virtually any data on the device," Yaswant stated. TrickMo is capable of intercepting OTPs, recording screens, remotely controlling the device, extracting data, and misusing accessibility services to gain permissions and perform actions without the user’s approval. Additionally, it can display misleading overlays designed to capture login credentials, enabling unauthorized financial transactions.

A particularly concerning discovery in Yaswant's findings is TrickMo’s ability to steal the device’s unlock pattern or PIN. This enables attackers to bypass security measures and access the device while it is locked. The malware achieves this by mimicking the legitimate unlock screen. “Once the user enters their unlock pattern or PIN, the page transmits the captured data, along with a unique device identifier,” Yaswant explained.

Zimperium’s researchers managed to gain entry to several C2 servers, identifying approximately 13,000 unique IP addresses linked to malware victims. The analysis revealed that TrickMo primarily targets regions such as Canada, the UAE, Turkey, and Germany. Yaswant’s investigation also uncovered millions of compromised records, with the stolen data including not only banking credentials but also access to corporate VPNs and internal websites, posing significant risks to organizations by potentially exposing them to larger-scale cyberattacks.

Global Resurgence of Grandoreiro Banking Trojan Hitting High

The cybercriminal group behind the Grandoreiro banking trojan has re-emerged in a global campaign since March 2024, following a significant law enforcement takedown earlier this year. This large-scale phishing operation targets over 1,500 banks across more than 60 countries, spanning Central and South America, Africa, Europe, and the Indo-Pacific, according to IBM X-ForceIBM X-Force. Originally focused on Latin America, Spain, and Portugal, Grandoreiro’s new campaign signifies a strategic shift after Brazilian authorities disrupted its infrastructure. 

Despite a major takedown in January 2024, which saw the Brazilian Federal Police, Interpol, the Spanish National Police, ESET, and Caixa Bank dismantle the operation and arrest five individuals, the malware has returned with significant upgrades. The phishing emails associated with Grandoreiro masquerade as urgent government payment requests, prompting recipients to click on links that download and execute malicious files. 

Once installed, the trojan interacts with banking apps to facilitate fraudulent transactions, logs keystrokes and captures screenshots to steal banking credentials and sensitive data. It also allows remote system manipulation and file operations by threat actors. A key enhancement in the latest version is a module that captures Microsoft Outlook data and uses compromised email accounts to spread spam. 

Grandoreiro employs the Outlook Security Manager tool to bypass security alerts, enabling seamless interaction with the Outlook client. IBM X-Force reports substantial improvements to the malware’s evasion techniques, including a string decryption method using AES CBC encryption with a unique decoder. The domain generation algorithm (DGA) has been upgraded with multiple seeds to enhance command and control (C2) communications. 

The trojan can also disable security alerts in Outlook and send phishing emails using compromised credentials. The updated Grandoreiro evades execution in several countries, including Poland, the Czech Republic, the Netherlands, and Russia. It also blocks operation on Windows 7 systems in the US without an active antivirus program, demonstrating its resilience and increased persistence. 

To combat the threat of Grandoreiro 

Organizations are advised to prioritize user education on phishing tactics. Employees should be trained to recognize suspicious emails, verify sender legitimacy, and avoid clicking on unknown links or opening untrusted attachments. Robust spam filtering systems at the gateway level can intercept many phishing emails, while behavior-based detection techniques in endpoint security systems can identify and stop harmful activities. As phishing attacks rise, protecting organizations becomes crucial. 

Enhancing user awareness is key, and resources like Phishing Tackle offer tools and training to help users recognize and avoid phishing threats. Despite technological defenses, user education remains vital in minimizing the impact of successful attacks. Consulting with experts can provide valuable insights and tools to strengthen defenses against these persistent threats.

Banking Malware "Brokewell" Hacks Android Devices, Steals User Data

Banking Malware "Brokewell" Hacks Android Devices

Security experts have uncovered a new Android banking trojan called Brokewell, which can record every event on the device, from touches and information shown to text input and programs launched.

The malware is distributed via a fake Google Chrome update that appears while using the web browser. Brokewell is in ongoing development and offers a combination of broad device takeover and remote control capabilities.

Brokewell information

ThreatFabric researchers discovered Brokewell while examining a bogus Chrome update page that released a payload, which is a common approach for deceiving unwary users into installing malware.

Looking back at previous campaigns, the researchers discovered that Brokewell had previously been used to target "buy now, pay later" financial institutions (such as Klarna) while masquerading as an Austrian digital authentication tool named ID Austria.

Brokewell's key capabilities include data theft and remote control for attackers.

Data theft 

  • Involves mimicking login windows of targeted programs to steal passwords (overlay attacks).
  • Uses its own WebView to track and collect cookies once a user logs into a valid website.
  • Captures the victim's interactions with the device, such as taps, swipes, and text inputs, to steal data displayed or inputted on it.
  • Collects hardware and software information about the device.
  • Retrieves call logs.
  • determines the device's physical position.
  • Captures audio with the device's microphone.

Device Takeover: 

  • The attacker can see the device's screen in real time (screen streaming).
  • Remotely executes touch and swipe gestures on the infected device.
  • Allows remote clicking on specific screen components or coordinates.
  • Allows for remote scrolling within elements and text entry into specific fields.
  • Simulates physical button presses such as Back, Home, and Recents.
  • Remotely activates the device's screen, allowing you to capture any information.
  • Adjusts brightness and volume to zero.

New threat actor and loader

According to ThreatFabric, the developer of Brokewell is a guy who goes by the name Baron Samedit and has been providing tools for verifying stolen accounts for at least two years.

The researchers identified another tool named "Brokewell Android Loader," which was also developed by Samedit. The tool was housed on one of Brokewell's command and control servers and is utilized by several hackers.

Unexpectedly, this loader can circumvent the restrictions Google imposed in Android 13 and later to prevent misuse of the Accessibility Service for side-loaded programs (APKs).

This bypass has been a problem since mid-2022, and it became even more of a problem in late 2023 when dropper-as-a-service (DaaS) operations began offering it as part of their service, as well as malware incorporating the tactics into their bespoke loaders.

As Brokewell shows, loaders that circumvent constraints to prevent Accessibility Service access to APKs downloaded from suspicious sources are now ubiquitous and widely used in the wild.

Security experts warn that device control capabilities, like as those seen in the Brokewell banker for Android, are in high demand among cybercriminals because they allow them to commit fraud from the victim's device, avoiding fraud evaluation and detection technologies.

They anticipate Brokewell being further improved and distributed to other hackers via underground forums as part of a malware-as-a-service (MaaS) operation.

To avoid Android malware infections, avoid downloading apps or app updates from sources other than Google Play, and make sure Play Protect is always turned on.

Beware, iPhone Users: iOS GoldDigger Trojan can Steal Face ID and Banking Details

 

Numerous people pick iPhones over Android phones because they believe iPhones are more secure. However, this may no longer be the case due to the emergence of a new banking trojan designed explicitly to target iPhone users.

According to a detailed report by the cybersecurity firm Group-IB, the Android trojan GoldDigger has now been successfully repurposed to target iPhone and iPad users. The company claims that this is the first malware designed for iOS, posing a huge threat by collecting facial recognition data, ID documents, and even SMS. 

The malware, discovered for the first time last October, now has a new version dubbed GoldPickaxe that is optimised for iOS and Android devices. When installed on an iPhone or Android phone, GoldPickaxe can collect facial recognition data, ID documents, and intercepted text messages, all with the goal of making it easier to withdraw funds from banks and other financial apps. To make matters worse, this biometric data is utilised to create AI deepfakes, which allow attackers to mimic victims and gain access to their bank accounts. 

It is vital to note that the GoldPickaxe malware is now targeting victims in Vietnam and Thailand. However, as with other malware schemes, if this one succeeds, the cybercriminals behind it may expand their reach to target iPhone and Android users in the United States, Europe, and the rest of the world. 

Android banking trojans are typically propagated via malicious apps and phishing campaigns. It is more difficult to install a trojan on an iPhone since Apple's ecosystem is more locked off than Google's. However, as hackers often do,they've figured out a way. 

Initially, the malware was disseminated via Apple's TestFlight program, which allows developers to deploy beta app versions without going through the App Store's authorization process. However, after Apple removed it from TestFlight, the hackers shifted to a more complicated way employing a Mobile Device Management (MDM) profile, which is generally used to manage enterprise devices. 

Given how successful a banking trojan like GoldDigger or GoldPickaxe can be, especially since it can target both iPhones and Android phones, this is unlikely to be the last time we hear about this spyware or the hackers behind it. As of now, even the most latest versions of iOS and iPadOS appear to be vulnerable to this Trojan. Group-IB has contacted Apple about the flaw, so a solution is likely in the works.

New Variant of Banking Trojan Discovered Targeting Mexico

In a recent discovery, cybersecurity researchers from Palo Alto Networks Unit 42 have uncovered a new variant of the stealthy banking Trojan known as Mispadu Stealer. This infostealer is specifically designed to target regions and URLs associated with Mexico, posing a significant threat to users in the region. 

The researchers stumbled upon this new variant while conducting investigations into attacks exploiting the Windows SmartScreen bypass vulnerability CVE-2023-36025. This vulnerability has been a prime target for cybercriminals looking to bypass security measures and infiltrate systems. However, it was addressed by Microsoft in November 2023. 

How You Are Being Attacked?

Essentially, attackers exploit a flaw in Windows SmartScreen, a security feature designed to warn users about potentially harmful downloads. By crafting internet shortcut files (.URL) or hyperlinks that point to malicious content, they can evade SmartScreen's defenses. This evasion tactic hinges on including a parameter that points to a network share rather than a standard URL. Inside the manipulated.URL file is a link leading to a network share controlled by the threat actor, housing a dangerous executable file. 

Since August 2022, Mispadu has been behind numerous spam campaigns, resulting in the theft of over 90,000 bank account credentials. This revelation highlights the significant threat Mispadu poses to the financial security of users across Latin America. However, Mispadu is just one member of a larger family of LATAM banking malware. 

Among its notorious counterparts is Grandoreiro, a formidable threat that has plagued users in the region. Recent efforts by law enforcement authorities in Brazil have resulted in the dismantling of Grandoreiro, offering some relief to users. 

Despite this success, cybersecurity experts warn that the danger from Mispadu and similar malware persists. Users are urged to remain vigilant when dealing with unsolicited emails and to bolster their defenses with robust security measures. By staying informed and implementing proactive strategies, users can better protect themselves against potential attacks.

Qbot: The Ever Expanding Malware Family

 

Given how widespread malware has become, new "families" of each type are being developed. Qbot, a family of malware that is used to steal data, falls under this category. 

Qbot's history 

As is sometimes the case with malware, Qbot (also referred to as Qakbot, Quakbot, or Pinkslipbot) wasn't identified until it was actually spotted in the wild. In the context of cybersecurity, the phrase "in the wild" describes a situation in which malware spreads unintentionally among targeted devices. As a kind of malware, Qbot is suspected to have existed at least as far back as 2007, making it much older than many of the more well-known varieties now in use. 

Simply because they are ineffective against new technology, several types of malware from the 2000s are no longer in use. But Qbot stands out in this case. Qbot has been running for at least 16 years as of the time of writing, an astonishing longevity for malware. 

Although this has also been interrupted by stretches of inactivity, Qbot has been routinely seen in use in the wild since 2007. In any event, cybercriminals continue to favour it as a choice. 

Qbot has changed throughout time and has been utilised by different hackers for a variety of purposes. Qbot started out as a Trojan, a virus that hides itself inside of software that seems to be safe. Data theft and remote access are only two of the many destructive uses for trojans. More precisely, Qbot targets banking credentials. It is regarded as a banking Trojan as a result. Is this still the case, though? How does Qbot function right now?

Modus operandi

The most notable type of the Qbot that is currently being spotted is an infostealer Trojan. Infostealer Trojans are intended to steal valuable data, including financial information, login passwords, and contact information, as their name implies. This particular strain of Qbot malware is mostly used to steal credentials. Variants of Qbot have also been seen engaging in keylogging, process hooking, and even system attacks using backdoors.

Qbot has been altered to have backdoor capabilities since it was first developed in the 2000s, making it an even greater threat. A backdoor is essentially an unauthorised method of accessing a network or system. Backdoors are frequently used by hackers to conduct their assaults because they provide a simpler entry point. This Qbot variation is referred to as "Backdoor.Qbot." 

Initially, the Trojan-like Emotet virus was used to propagate Qbot. Nowadays, malicious email campaigns using attachments are the main way that Qbot is disseminated. Large quantities of spam are sent during such campaigns to hundreds or even thousands of recipients in the hopes that some of the users who are being targeted would respond. 

Qbot has frequently been seen as a.zip file with an XLS dropper that contains macros inside malicious email attachments. Malware can be installed on a recipient's device if they open a malicious attachment, frequently without their awareness. Exploit kits can also be used to propagate Qbot. These are instruments that help cybercriminals spread malware. 

Exploit kits can identify security flaws in a device's construction and then take advantage of such flaws to get unauthorised access. 

However, things continue even after backdoors and password theft. Operators of Qbots have been crucial Initial Access Brokers. These are cybercriminals who offer other hostile actors system access for sale. Access has been allowed to some very large organizations, including the ransomware-as-a-service provider REvil, in the instance of the Qbot perpetrators. In fact, a number of ransomware partners have been seen employing Qbot to get initial access to systems, giving the malware yet another alarming use.

Qbot is used to target a variety of industries and has surfaced in numerous harmful activities. Qbot has targeted manufacturing enterprises, government agencies, banking websites, healthcare organizations, and more. 2020 data from TrendMicro indicated that 28.1% of Qbot's targets are in the healthcare industry. 

In the same analysis, TrendMicro also noted that the US, China, and Thailand had the greatest rates of Qbot detection in 2020. Qbot is obviously a worldwide danger because it was also frequently detected in Australia, Germany, and Japan. 

Mitigation tips

It's crucial that you are aware of the signs of malicious mail because Qbot is frequently disseminated through spam campaigns. 

Starting with the contents, there are many warning signs that an email may be malicious. It's advisable to avoid clicking any links or attachments from new email addresses until you are certain they can be trusted. You may check a URL's validity on a number of link-checking websites to see whether it is safe to click or not. 

The file extensions.pdf,.exe,.doc,.xls, and.scr are among those that are frequently used to propagate malware. Although not the only file extensions used to spread malware, these are among the most popular kinds, so be on the lookout for them when you receive emails with attached files. 

Additionally, you should exercise caution if an email from a new sender carries a sense of urgency. In order to persuade victims to comply, cybercriminals frequently utilise persuasive language in their emails.

Beware of this Android Banking Trojan that Steals Banking Credentials

 

A financial trojan called "Godfather" which is capable of stealing account credentials from more than 400 different banking and cryptocurrency apps is presently targeting Android users in 16 other countries. 

According to a recent report from the cybersecurity company Group-IB, the Godfather trojan, which was initially uncovered by ThreatFabric back in March of last year, has been dramatically upgraded and updated since then. 

In a second report, the dark web and cybercrime monitoring company Cyble describes how Godfather is also being disseminated in Turkey through a malicious app that has been downloaded 10 million times and pretends to be a well-known music application. 

Godfather is thought to be the replacement for Anubis, a well-known and widely-used banking Trojan before it lost the capacity to get past updated Android defenses, BleepingComputer reported. 

Banking and cryptocurrency apps on the hit list 

The banking trojan has targeted users of more than 400 apps since it first debuted last year, including 215 banking apps, 94 cryptocurrency wallets, and 110 crypto trading platforms. The malware also targeted 49 banking apps in the US, 31 in Turkey, 30 in Spain, 22 in Canada, 20 in France, 19 in Germany, and 17 in the UK, among other nations. 

Surprisingly, Group-IB discovered a section in Godfather's code that stops the malware from aiming for users from former Soviet Union nations and users in Russia, indicating that its developers speak Russian. The malware checks the system language on an Android device after installation to see if it is Russian, Azerbaijani, Armenian, Belarusian, Kazakh, Kyrgyz, Moldovan, Uzbek, or Tajik. If so, Godfather shuts down and doesn't attempt to steal any stored cryptocurrency or banking accounts.

Modus operandi 

Godfather attempts to acquire persistence on an Android phone after being installed via a malicious app or file by impersonating Google Protect. Once you download an app from the Google Play Store, this genuine software begins to execute. 

The banking trojan then claims to be "scanning" when, in fact, it is hiding its icon from the list of installed apps and creating a pinned "Google Project" notice. Because of this, malware is more likely to blend into the background and is more challenging to remove. 

A targeted user goes about their normal activities because Godfather's symbol is missing. To steal user passwords and empty their accounts, the malware then applies false overlays to well-known banking and cryptocurrency apps. Additionally, Godfather employs a smart tactic to direct people to phishing websites. It accomplishes this by displaying a fake notification that impersonates one of its smartphone's loaded banking or cryptocurrency apps. 

In addition to stealing credentials, the malware is able to record a user's screen, launch keyloggers to capture their keystrokes, route calls to get around two-factor authentication (2FA), and send SMS messages from infected devices. 

Mitigation Tips 

Installing new apps from a third party other than the Google Play Store or other official app stores like the Amazon App Store or Samsung Galaxy Store puts you at risk for Godfather and other Android malware. While sideloading apps could be alluring, since they are uploaded without any security checks, they may be infected with malware and other viruses. 

Additionally, make sure Google Play Protect is turned on so that it can scan both new and old apps for malware. However, you might also want to download one of the top Android antivirus apps for additional security.

SharkBot Malware Targets Thousands of Android Users Via Disguised File Manager App

 

Variants of the SharkBot banking trojan were identified in multiple file manager Android applications on the Google Play Store, some of them with thousands of downloads. 

The majority of users who downloaded the trojanized apps were located in the U.K. followed by Italy, Iran, and Germany, security researchers at Bitdefender said in an analysis published this week. 

"The Google Play Store would likely detect a trojan banker uploaded to their repository, so criminals’ resort to more covert methods," reads the advisory. One way is with an app, sometimes legitimate with some of the advertised features, that doubles as a dropper for more insidious malware." 

This was the case with multiple file manager apps, which were disguised as such to justify the request for permission to install external packages from the user. 

The permissions asked by trojanized apps included READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, GET_ACCOUNTS, REQUEST_INSTALL_PACKAGES, QUERY_ALL_PACKAGES, and REQUEST_DELETE_PACKAGES. 

"Of course, that permission is used to download malware," the researchers wrote. "As Google Play apps only need the functionality of a file manager to install another app and the malicious behavior is activated to a restricted pool of users, they are challenging to detect." 

While the applications identified by the researchers are no longer available on the Play Store, they can still be downloaded via multiple third-party stores, making them a huge threat. 

The first app examined by the researchers was 'X-File Manager,' designed by 'Viktor Soft ICe LLC' and counting over 10,000 installs before it was taken down by Google. 'FileVoyager' was the second one, manufactured by 'Julia Soft Io LLC' with nearly 5,000 downloads. 

The researchers discovered two more apps following an identical methodology, but they were never present on the Google Play store. They are called 'Phone AID, Cleaner, Booster' and 'LiteCleaner M' and were identified on the web via third-party app stores. 

The advisory published by the Bitdefender team comes weeks after threat analysts at Cleafy indicated the Android banking Trojan Vultur has reached more than 100,000 downloads on the Google Play Store.

Users who have downloaded the malicious apps are advised to delete them and change their bank account passwords immediately. Additionally, users are recommended to enable Play Store Protect and scan app ratings and reviews before downloading them.

Threat Actors Exploit WeTransfer to Spread Lampion Malware

 

In a new phishing campaign unearthed by Cofense researchers, the Lampion malware is being distributed massively, with hackers exploiting WeTransfer as part of their campaign.

WeTransfer is an internet-based computer file transfer service that can be utilized free of cost, hence it's a no-cost way to circumvent security software that may not detect URLs in emails. 

The malware authors are sending phishing emails from exploited firm accounts requesting customers to download a "Proof of Payment" document from WeTransfer. 

The file sent to the targets is a ZIP archive containing a VBS (Virtual Basic script) file that the user must open in order for the attack to begin. Upon clicking on the file, the script launches a WScript process that manufactures four VBS files with random names. The first is empty, the second has limited functionality, and the third's sole motive is to launch the fourth script. 

According to Cofense researchers, this extra step is unclear, but modular execution approaches are typically preferred for their versatility, allowing easy file swaps. The fourth script initiates a new WScript process that links to two hardcoded URLs to retrieve two DLL files concealed inside password-protected ZIPs. The malicious links lead to Amazon AWS instances. 

The ZIP file password is concealed in the script, so the archives are extracted without user communication. The contained DLL payloads are loaded into memory, allowing Lampion to be stealthily executed on compromised systems. 

Subsequently, the malware initiates extracting data from the computer, and bank accounts, and overlaying its own login forms on login pages. These fake bogus forms are stolen and sent to the hacker when users enter their credentials. 

The Lampion trojan has been active since at least 2019, primarily targeting Spanish-speaking users and employing exploited servers to deploy its malicious ZIPs. 

Last year, the malware was identified exploiting cloud services for hosting the malware for the first time, including Google Drive and pCloud. Recently, in March 2022, Cyware reported an increase in trojan distribution, identifying a hostname link to Bazaar and LockBit operations.

Prevention Tips 

Researchers advised users to apply the following mitigations to defend against malware attacks: 
  • Update software, including operating systems, applications, and firmware frequently 
  • Install OS patches when they are available 
  • Enforce MFA to the greatest extent possible 
  • If you use RDP and/or other potentially risky services, secure and monitor them closely 
  • Employ cryptographic vaults for data safety

Google Removes Several Apps From Play Store Distributing Malware

 

Earlier this week, Google blocked dozens of malicious Android apps from the official Play Store that were propagating Joker, Facestealer, and Coper malware families via the virtual marketplace. 

According to the findings from Zscaler ThreatLabz and Pradeo researchers, the Joker spyware exfiltrated SMS messages, contact lists, and device information and lured victims to sign up for premium service subscriptions. 

A total of 54 Joker downloader apps were unearthed by the two cybersecurity firms, with the apps installed cumulatively over 330,000 times. Nearly half of the apps belonged to communication (47.1%) category followed by tools (39.2%), personalization (5.9%), health and, photography. 

“The tools and communication were among the most targeted categories covering the majority of the Joker-infected apps. ThreatLabz discovered daily uploads of apps containing the Joker malware indicating the high activity level and persistence of the adversary group.” reads the blog post published by Zscaler. “Consistent with previous findings, ThreatLabz's latest discoveries belonging to the Joker malware campaign continue to follow similar developer naming patterns and use of familiar techniques.” 

ThreatLabz experts also uncovered multiple apps compromised with the Facestealer and Coper malware. 

The Facestealer spyware was first unearthed in July last year by Dr. Web researchers, and was designed to steal Facebook users’ logins and passwords and authentication tokens. 

The Coper malware is a banking trojan that targets banking applications in Europe, Australia, and South America. The hackers distribute the apps by disguising them as legitimate apps in the Google Play Store. 

“Once downloaded, this app unleashes the Coper malware infection which is capable of intercepting and sending SMS text messages, making USSD (Unstructured Supplementary Service Data) requests to send messages, keylogging, locking/unlocking the device screen, performing overly attacks, preventing uninstalls and generally allowing attackers to take control and execute commands on infected device via remote connection with a C2 server.” continues the report. 

The researchers recommended users to refrain from granting unnecessary permissions to apps and verify their authenticity by checking for developer information, reading reviews, and scrutinizing their privacy policies. If you become a victim of a malicious app from the Play Store, inform Google about it immediately through the support options in your play Store app.

This Banking Trojan is Targeting Users of Spanish Financial Services

 

A previously unreported Android banking trojan targeting users of the Spanish financial services business BBVA has been spotted in the wild. 

The malware, named 'Revive' by Italian cybersecurity firm Cleafy and believed to be in its early stages of development, was first discovered on June 15, 2022, and propagated via phishing operations. 

"The name Revive has been chosen since one of the functionality of the malware (called by the [threat actors] precisely 'revive') is restarting in case the malware stops working," Cleafy researchers Federico Valentini and Francesco Iubatti said in a Monday write-up. 

Downloadable from malicious phishing websites ("bbva.appsecureguide[.]com" or "bbva.european2fa[.]com"), the malware impersonates the bank's two-factor authentication (2FA) app as a bait to mislead users into installing the software and is reported to be inspired by open-source spyware dubbed Teardroid, with the authors altering the original source code to integrate new features.

In contrast to other banking malware that are known to target a wide range of financial apps, Revive is targeted for a single target, in this case, the BBVA bank. However, it is similar to its competitors in that it uses Android's accessibility services API to achieve its operational goals. 

Revive is primarily designed to gather the bank's login credentials via lookalike websites and allow account takeover attacks. It also has a keylogger module to record keystrokes and the ability to intercept SMS messages sent by the bank, particularly one-time passwords and two-factor authentication codes. 

"When the victim opens the malicious app for the first time, Revive asks to accept two permissions related to the SMS and phone calls. After that, a clone page (of the targeted bank) appears to the user and if the login credentials are inserted, they are sent to the [command-and-control server] of the TAs," the researchers further stated.

The findings emphasise the importance of exercising caution while installing software from unknown third-party sources.

Malicious Excel Files are Now Being Employed to Propagate Revamped Emotet Malware

 

Cybersecurity researchers discovered that the infamous Emotet malware has altered methods yet again. In its latest campaign, the malware is able to access and use spreadsheets, documents, and other Microsoft programs, evading entry security. 

Emotet was identified in 2014 as a banking trojan, and it has been quite active in recent years. In this campaign, the botnet authors are using a relatively new module that steals payment card information from Google Chrome. 

According to Deep Instinct researchers, the current version of Emotet has led to a nine-fold surge in the use of Microsoft Excel macros compared with what researchers detected in the fourth quarter of 2021. The hackers that utilized this trojan were among the first to offer malware-as-a-service (MaaS). 

The latest malware still uses many of the same attack vectors as it had in the past, but this new technique is seen as being more effective in collecting and using stolen credentials. 

In a blog post on the re-emergence of Emotet, Chuck Everette, director of cybersecurity advocacy for Deep Instinct, which has been following the malware since the fourth quarter of last year, noted that the current malware variant uses many of the same “evasion methods” as previous versions. 

The malware has targeted customers in Japan, as well as the United States and Italy since this spring. The researchers detected the Emotet's re-emergence last November, and they noted that this evolved malware was even able to get past email gateway security. 

Additionally, the banking trojan is employing 64-bit shell code, as well as more advanced PowerShell and active scripts, “with nearly a fifth of all malicious samples exploiting the 2017 Microsoft vulnerability CVE-2017-11882,” according to reports. 

"We use internal code and binary similarity algorithms on our cloud backend to associate and correlate new variants of a select set of campaigns which we monitor very closely, Emotet being one of them," he explained. 

In particular, multiple static evasion methods are very characteristic of Emotet, and upticks in those in new variant waves are very indicative of malware activity. 

“The Emotet Gang are professionals. They know how to run a successful phishing campaign and have now upped their game with new sophisticated attack techniques,” Everette explained on his company’s blog on the re-emergence of Emotet. However, the primary delivery method is still phishing emails, and the human factor is the weakness. If you make yourself more difficult to attack than another company, they will go after the easier target. Make sure you're the harder target to penetrate. Educate your employees."

This Android-wiping Malware is Evolving into a Constant Threat

 

The threat actors responsible for the BRATA banking trojan have refined their techniques and enhanced the malware with data-stealing capabilities. Cleafy, an Italian mobile security business, has been following BRATA activity and has discovered variations in the most recent campaigns that lead to extended persistence on the device. 

"The modus operandi now fits into an Advanced Persistent Threat (APT) activity pattern. This term is used to describe an attack campaign in which criminals establish a long-term presence on a targeted network to steal sensitive information," explains Cleafy in a report this week.

The malware has also been modified with new phishing tactics, new classes for requesting further device permissions, and the inclusion of a second-stage payload from the command and control (C2) server. BRATA malware is also more focused, as researchers determined that it concentrates on one financial institution at a time and only switches to another when countermeasures render its attacks ineffective.

For example, instead of getting a list of installed applications and retrieving the appropriate injections from the C2, BRATA now comes pre-loaded with a single phishing overlay. This reduces harmful network traffic as well as interactions with the host device. 

In a later version, BRATA gains greater rights to transmit and receive SMS, which can aid attackers in stealing temporary codes such as one-time passwords (OTPs) and two-factor authentication (2FA) that banks send to their clients. After nesting into a device, BRATA retrieves a ZIP archive containing a JAR ("unrar.jar") package from the C2 server. 

This keylogging utility tracks app-generated events and records them locally on the device along with the text contents and a timestamp. Cleafy's analysts discovered that this tool is still in its early stages of development. The researchers believe the author's ultimate purpose is to exploit the Accessibility Service to obtain data from other apps. 

BRATA's development 

In 2019, BRATA emerged as a banking trojan capable of screen capture, app installation, and turning off the screen to make the device look powered down. BRATA initially appeared in Europe in June 2021, utilising bogus anti-spam apps as a lure and employing fake support personnel who duped victims and fooled them into handing them entire control of their devices. 

In January 2022, a new version of BRATA appeared in the wild, employing GPS tracking, several C2 communication channels, and customised versions for different locations. Cleafy has discovered a new project: an SMS stealer app that talks with the same C2 infrastructure as the current BRATA version and the shift in tactics. 

It uses the same structure and class names as BRATA but appears to be limited to syphoning brief text messages. It currently targets the United Kingdom, Italy, and Spain. To intercept incoming SMS messages, the application requests that the user designate it as the default messaging app, as well as authorization to access contacts on the device. 

For the time being, it's unclear whether this is only an experiment in the BRATA team' to produce smaller apps focused on certain roles. What is obvious is that BRATA continues to evolve at a two-month interval. It is critical to be watchful, keep your device updated, and avoid installing apps from unapproved or dubious sources.

Emotet : The Infamous Botnet Has Returned

 

Kaspersky researchers were able to retrieve and analyze 10 out of 16 modules, with most having been used by Emotet in the past in one form or another. Kaspersky Lab was created in 1997 as multinational cybersecurity and digital privacy organization. Kaspersky's deep risk intelligence and security expertise are continually evolving into new security solutions and services to safeguard enterprises, vital infrastructure, governments, and consumers all around the world. 

Emotet was discovered in the wild for the first time in 2014. Its major purpose back then was to steal user's financial credentials. Since then, it has gone through several modifications, began transmitting other viruses, and eventually evolved into a strong botnet. Emotet is a type of malware classified as banking Trojans. Malspam, or spam emails with malware, is the most common way for it to propagate. To persuade users, these communications frequently contain familiar branding, imitating the email structure of well-known and trustworthy companies such as PayPal or DHL. 

As per Kaspersky telemetry, the number of victims increased from 2,843 in February 2022 to 9,086 in March 2022, indicating the attackers targeted more than three times the number of users. As a result, the number of threats detected by Kaspersky solutions has increased, from 16,897 in February 2022 to 48,597 in March 2022. 

A typical Emotet infection starts with spam e-mails containing malicious macros in Microsoft Office attachments. The actor can use this macro to launch a malicious PowerShell command which will drop and start a module loader, which will then talk with a command and control server to download and start modules. In the percent Windows percent SysWOW64 or percent User percent AppDataLocal directory, Emotet creates a subfolder with a random name and replicates itself under a completely random name and extension. The exported Control RunDLL method is used to launch the Emotet DLL's primary activity. These modules can be used to carry out a range of actions on the infected computer. Kaspersky researchers were able to extract and evaluate 10 of the 16 modules, the majority of which had previously been utilized by Emotet. 

Researchers now state that the Emotet can download 16 modules judging by the recent Emotet protocol and C2 answers. They were able to recover ten of them (including two separate copies of the Spam module), which were utilized by Emotet to steal credentials, passwords, accounts, and e-mail addresses, as well as spam. We present a brief examination of these modules and also statistics on current Emotet attacks in this post. 

To gather the account details of various email clients, the current version of Emotet can create automated spam campaigns which are further spread down the network from infected devices, retrieving emails and email addresses from Thunderbird and Outlook apps and accumulating passwords from popular web browsers like Internet Explorer, Mozilla Firefox, Google Chrome, Safari, and Opera. 

Emotet infects computers in businesses and homes all around the world. As per our telemetry, Emotet most frequently targeted users from the following countries in Q1 2022: Italy (10.04%), Russia (9.87%), Japan (8.55%), Mexico (8.36%), Brazil (6.88%), Indonesia (4.92%), India (3.21%), Vietnam (2.70%), China (2.62), Germany (2.19%) and Malaysia (2.13%). 

The present set of components is capable of a wide range of malicious activities, including stealing e-mails, passwords, and login data from a variety of sources, as well as spamming. Except for the Thunderbird components, Emotet has utilized all of these modules in some form or another before. However, there are still a few modules that we haven't been able to get our hands-on.

Octo: A New Malware Strain that Targets Banking Institutions

 

Last year, an Android banking malware strain was found in the open, few organizations called it "Coper," belonging to a new family, however, ThreatFabric intelligence hinted it as a direct inheritance of the infamous malware family Exobot. Found in 2016, Exobot used to target financial institutions until 2018, these campaigns were focused in France, Turkey, Thailand, Germany, Japan, and Australia. Following the incident, another "lite" variant surfaced, named ExobotCompact by the developer famous as "Android" on the dark web. 

Analysts from ThreatFabric established a direct connection between ExobotCompact and the latest malware strain, named "ExobotCompact.B." The latest malware strain surfaced in November 2021, named ExobotCompact.D. "We would like to point out that these set of actions that the Trojan is able to perform on victim’s behalf is sufficient to implement (with certain updates made to the source code of the Trojan) an Automated Transfer System (ATS)," says ThreatFabric report. The recent actions by this malware family involve distribution via various malicious apps on Google Play Store. 

The apps were installed more than 50k times, targeting financial organizations around the world, including broad and generic campaigns having a high number of targets, along with focused and narrow campaigns across Europe. Earlier this year, experts noticed a post on a dark web forum, a user was looking for an Octo Android botnet. Later, a direct connection was found between ExobotCompact and Octo. Interestingly, ExobotCompact was updated with various features and rebranded as Octo, bringing remote access capability, therefore letting malicious actors behind the Trojan to perform on-device fraud (ODF). 

ODF is the riskiest, most dangerous fraud threat. Here, transactions begin from the same device that a target uses on a daily basis. Here, anti-fraud programmes are challenged to detect the scam activity with less in number malicious indicators and different fraud done via different channels. ThreatFabric reports, "to establish remote access to the infected device, ExobotCompact.D relies on built-in services that are part of Android OS: MediaProjection for screen streaming and AccessibilityService to perform actions remotely."

Hackers Exploit Microsoft Exchange for IcedID Reply-Chain Hijacking Attacks

 

Cybersecurity researchers at Intezar, an Israeli security firm have identified a brand-new electronic mail phishing campaign employing the conversation hijacking strategy to ship the IcedID info-stealing malware onto compromised devices by making use of vulnerable Microsoft Change servers. 

"The emails use a social engineering technique of conversation hijacking (also known as thread hijacking)," researchers Joakim Kennedy and Ryan Robinson explained. "A forged reply to a previous stolen email is being used as a way to convince the recipient to open the attachment. This is notable because it increases the credibility of the phishing email and may cause a high infection rate." 

The most recent wave of attacks, spotted in mid-March 2022, is believed to have targeted businesses within the energy, healthcare, law, and pharmaceutical sectors. IcedID, (also known as BokBot) is a banking trojan-type malware that has advanced to turn into an entry-level for more refined threats, together with human-operated ransomware and the Cobalt Strike adversary simulation device. 

The banking trojan has the capability of communicating with a remote server and downloading next-stage implants and software that allow malicious actors to perform follow-on activities and move laterally throughout impacted networks to spread additional malware. 

Last year in June 2021, American enterprise security company Proofpoint revealed an evolving strategy within the cybercrime panorama whereby preliminary access brokers were spotted invading target networks via first-stage malware payloads equivalent to IcedID to deploy Egregor, Maze, and REvil ransomware payloads. 

Previously IcedID campaigns employed website contact forms to deliver malware-laced links to organizations, the present model of the campaign banks on susceptible Microsoft Change servers to ship the lure emails from a hijacked account, indicating a further evolution of the social engineering scheme.

"The payload has also moved away from using Office documents to the use of ISO files with a Windows LNK file and a DLL file," researchers added. "The use of ISO files allows the threat actor to bypass the Mark-of-the-Web controls, resulting in execution of the malware without warning to the user." 

To make the phishing emails seem more legitimate, the victim’s email address is used to send fraudulent replies to an already existing email thread plundered from the compromised individual’s account. 

"The use of conversation hijacking is a powerful social engineering technique that can increase the rate of a successful phishing attempt. By using this approach, the email appears more legitimate and is transported through the normal channels which can also include security products,” the researchers concluded.

The Emotet Malware is Alive and Using TrickBot to Rebuild its Botnet

 

The malicious Emotet botnet, which made a comeback in November 2021 after a 10-month break, is showing indications of steady expansion once again, collecting a colony of over 100,000 infected hosts to carry out its destructive actions. 

In a new round of attacks, Emotet, a Banking Trojan which has evolved into a formidable modular threat, has reappeared with improved features. It has infected devices to carry out additional spam campaigns and install various payloads like the QakBot (Qbot) and Trickbot malware. These payloads would subsequently be utilized to give threat actors, such as Ryuk, Conti, ProLock, Egregor, and others, early access to deploy ransomware. 

"While Emotet has not yet reached the same magnitude as before, the botnet is displaying a strong resurrection with a total of around 130,000 unique bots scattered over 179 countries since November 2021," Lumen's Black Lotus Labs researchers wrote in a report. On April 25th, 2021, German law enforcement used the network to send an Emotet module that removed the malware from afflicted devices. 

The TrickBot malware has begun to dump an Emotet loader on affected devices, according to Emotet research group Cryptolaemus, GData, and Advanced Intel. While Emotet used to deploy TrickBot, the threat actors now use a mechanism called "Operation Reacharound" by the Cryptolaemus group, which rebuilds the botnet utilizing TrickBot's current infrastructure. 

Apart from command-and-control (C2) lists and RSA keys, which change from version to version, Emotet's main payload hasn't changed much, but the list of phrases used to establish a process name for its bot has been renewed. Along with new binaries, words like engine, finish, magnify, resapi, query, skip, and many more are utilized and modified. Researchers may be able to construct signatures to detect Emotet infections on machines once these lists have been secured, but signature-based detection is more challenging if the list changes. 

Abuse.ch has published a list of the new Emotet botnet's command and control servers and strongly advises network administrators to ban the linked IP addresses. Another new feature is the ability to collect extra system information from compromised workstations in addition to a list of running processes. The number of bots and associated dispersion are crucial indicators of Emotet's success in reconstructing its once-vast infrastructure.

10K Victims Infested via Google Play 2FA App Loaded with Banking Trojan

 

The Vultur trojan obtains bank credentials but then requests authorization to inflict even more damage later. 

A fraudulent two-factor authentication (2FA) software has been deleted from Google Play after being available for more than two weeks — but not before it was downloaded more than 10,000 times. The Vultur stealer malware, which targets and swoops down on financial information, is put into the app, which is completely functioning as a 2FA authenticator. 

Researchers at Pradeo warn users who have the malicious app, just named "2FA Authenticator," to delete it straight away since they are still at risk — both from banking-login theft and other assaults made possible by the app's broad over permissions. 

Using open-source Aegis authentication code combined with malicious add-ons, the threat actors constructed an operable and convincing app to mask the malware dropper. According to a Pradeo analysis issued, this enabled it to proliferate unnoticed via Google Play. 

“As a result, the application is successfully disguised as an authentication tool, which ensures it maintains a low profile,” the report added. 

The Vultur banking trojan is installed once the software is downloaded, and it harvests financial and banking data from the affected smartphone, among other things. The Vultur remote access trojan (RAT) malware, initially discovered by ThreatFabric investigators in March, was the first of its type to employ keylogging and screen recording as its main approach for stealing banking data, allowing the organisation to systematize and expand the process of stealing credentials. 

“The actors chose to steer away from the common HTML overlay strategy we usually see in other Android banking trojans: this approach usually requires more time and effort from the actors to steal relevant information from the user. Instead, they chose to simply record what is shown on the screen, effectively obtaining the same end result,” ThreatFabric said at the time. 

According to the Pradeo team, the fake 2FA authenticator also requests device rights that aren't shown in the Google Play profile. The attackers can use those tricksy, enhanced privileges to do things like access user location data so attacks can be aimed at specific regions, disable device lock and password security, download third-party apps, and take control of the device even if the app is shut down, according to the report. 

Once the device is fully hacked, the app installs Vultur, “an advanced and relatively new kind of malware that mostly targets online banking interface to steal users’ credentials and other critical financial information,” the report said. 

Pradeo discovered another sneaky tactic used by the malicious 2FA by acquiring the SYSTEM ALERT WINDOW permission, which allows the application to modify the interfaces of other mobile apps. 

"Very few apps should use this permission; these windows are intended for system-level interaction with the OS," Google stated. 

Despite the fact that the researchers reported their disclosure to Google Play, the malicious 2FA Authenticator app loaded with the banking malware remained accessible for 15 days, according to the Pradeo team.

Threat Actors Blanket Androids with Flubot & Teabot Campaigns

 

Researchers have found a bundle of dynamic campaigns transmitting the Flubot and Teabot trojans through a variety of delivery strategies, with threat actors utilizing smishing and pernicious Google Play applications to target victims with fly-by assaults in different locations across the globe. 

Specialists from Bitdefender Labs said they have caught more than 100,000 malignant SMS messages attempting to transmit Flubot malware since the start of December, as indicated by a report distributed Wednesday. 

During their analysis of Flubot, the team additionally found a QR code-peruser application that has been downloaded more than 100,000 times from the Google Play store and which has disseminated 17 different Teabot variations, they said. 

Flubot and Teabot surfaced on the scene last year as somewhat clear financial trojans that take banking, contact, SMS and different kinds of private information from infected gadgets. Be that as it may, the administrators behind them have interesting strategies for spreading the malware, making them especially nasty and expansive. 
 
Flubot was first founded in April focusing on Android clients in the United Kingdom and Europe using noxious SMS messages that nudged recipients to introduce a "missed package delivery" application, exhibiting a component of the malware that allows attackers to utilize command and control (C2) to send messages to victims. 

This feature permits administrators to rapidly change targets and other malware highlights on the fly, augmenting their assault surface to a worldwide scale without requiring a complex framework. For sure, campaigns later in the year targeted Android users in New Zealand and Finland. 

“These threats survive because they come in waves with different messages and in different time zones,” Bitdefender researchers wrote in the report. 

“While the malware itself remains pretty static, the message used to carry it, the domains that host the droppers, and everything else is constantly changing. For example, in the month between Dec. 1 of last year and Jan. 2 of this year, the malware was highly active in Australia, Germany, Spain, Italy and a few other European countries.”   

Campaigns between Jan. 15 and Jan. 18 then, at that point, moved to different parts of the globe, including Romania, Poland, the Netherlands, Spain and even Thailand, they found. 
 
Attackers likewise spread out past attempting to fool users into thinking they missed a package delivery- what Bitdefender named "fake courier messages" - to disseminate Flubot. However this strategy was available in almost 52% of campaigns specialists noticed, they likewise utilized a trick named "is this you in this video" that is a take-off of a credential-stealing campaign that has been streaming steadily via web-based media in around 25% of noticed missions, analysts wrote. 

“When the victim clicks on the link, it usually redirects them to a fake Facebook login that gives attackers direct access to credentials,” researchers explained. 

Flubot administrators have gotten on this trick and are involving a variety of it in one of the smishing efforts noticed, with clients getting an SMS message that inquires, "Is this you in this video?" researchers noted. In any case, the objective of the mission is very similar: to some way or another trick users into installing the software under some cover. 

“This new vector for banking trojans shows that attackers are looking to expand past the regular malicious SMS messages.”
  
Among different lures, Flubot administrators likewise utilized SMS messages utilizing counterfeit program updates and phoney phone message notices in around 8% of noticed campaigns, separately, analysts stated.
