Cybersecurity researchers at Zscaler ThreatLabz have uncovered a concerning trend in which cybercriminals are exploiting popular web hosting and blogging platforms to disseminate malware and steal sensitive data. This sophisticated tactic, known as SEO poisoning within the realm of Black Hat SEO techniques, has been employed to manipulate search engine results, pushing fraudulent websites to the forefront of users' search queries, thereby increasing the risk of unwittingly accessing malicious content.
How They Operate
The cybercriminals orchestrating these operations have devised intricate strategies to evade detection and entice unsuspecting users into downloading malware. They fabricate fraudulent websites spanning a wide array of topics, ranging from pirated software to culinary recipes, often hosted on well-established platforms such as Weebly. By adopting the guise of legitimate sites, complete with endorsements like "Powered by Weebly," they exploit users' trust in reputable services to perpetrate their malicious activities.
The process commences with cybercriminals setting up sham sites on web hosting services, adeptly avoiding detection by both hosting providers and users. When individuals search for relevant content and click on links from search results, they unknowingly find themselves on these malevolent sites. To circumvent scrutiny from security researchers, the perpetrators implement evasion techniques, including scrutinising referral URLs. Should a user access the site directly, indicating a potential analysis, the site tactfully sidesteps redirection to preserve its cloak of invisibility.
The Payload Delivery System
Malicious payloads are secretly delivered through multi-layered zipped files concealed within seemingly innocuous content. For instance, an individual seeking cracked software may inadvertently download malware instead of the anticipated content. Upon execution, the malware puts together a sequence of activities, encompassing process hollowing and DLL sideloading, aimed at downloading additional malware and establishing communication with command-and-control servers.
Tricks to Avoid Detection
To further complicate their activities, threat actors employ techniques, including string concatenation, mathematical manipulation, and the utilisation of password-protected ZIP archives. These tactics serve to confound security measures, rendering the malicious code arduous to decipher and bolstering the malware's ability to slightly pass over detection.
Data Theft and Deceptive Tactics
Once ensconced within a system, the malware embarks on an mission to harvest extensive troves of data, encompassing system information, browser data, credentials, and browsing history. Additionally, it sets its sights on emails pertaining to cryptocurrency exchanges, adeptly modifying email content and intercepting one-time authentication codes to facilitate unauthorised access.
How To Protect Yourself?
Keeping in mind such campaigns, users are advised to exercise utmost caution when procuring software from unfamiliar sources and to prioritise visiting reputable websites. Staying abreast of emerging cybersecurity threats and securing defences with robust protocols can substantially mitigate the risk of succumbing to potential infections.
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.
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.
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.
In an unsettling situation, cybercriminals are increasingly turning to credential theft as a lucrative business, aided by the rise of infostealer malware attacks. Over the past three years, these threat actors have capitalised on the opportunity, compromising millions of personal and corporate devices globally.

Kaspersky researchers highlight various sales models, with prices starting at $10 per log file.
Emerging Dark Web Hubs
Darknet markets have become key enablers of cybercrime, facilitating the sale of stolen credentials and victim profiles to cybercriminal groups. Following the takedown of Genesis Market, new hubs like Kraken Market and DNM Aggregator have emerged, offering seamless payment options via crypto processors.
Regional Impact
Regions like the Asia-Pacific and Latin America have been particularly affected by credential stealing attacks, with millions of credentials stolen from countries like Brazil, India, Colombia, and Vietnam. In Australia, compromised credentials accounted for the majority of cybersecurity incidents, with compromised or stolen credentials implicated in 56% of all incidents.
The Role of Initial Access Brokers
The number of initial access brokers (IABs) operating worldwide has risen significantly, with the APAC region experiencing a particularly sharp increase. These brokers play a critical role in fueling cybercrime operations, selling access to corporate networks and facilitating activities like ransomware attacks.
Despite the perception of cyberattacks as complex operations, the reality is that many exploit the simplicity of credential vulnerabilities. According to the Cybersecurity and Infrastructure Security Agency (CISA), over half of government and critical infrastructure attacks leverage valid credentials, with stolen credentials implicated in 86% of breaches involving web-based platforms. Credential stuffing, a technique where attackers use stolen usernames and passwords on various websites, has become increasingly popular due to individuals' tendency to reuse login information for convenience.
With cybercriminals exploiting vulnerabilities in corporate and personal networks, organisations and individuals must remain a step ahead to protect against this pervasive threat.
An exposé has brought to light an intricate operation engineered by the TA558 hacking group, known for its previous focus on the hospitality and tourism sectors. This new offensive, dubbed "SteganoAmor," employs steganography, a technique of concealing malicious code within seemingly harmless image files, to infiltrate targeted systems worldwide. Positive Technologies, the cybersecurity firm behind the discovery, has identified over 320 instances of this attack affecting various organisations across different sectors and countries.
How SteganoAmor Attacks Work
SteganoAmor attacks start with sneaky emails that look harmless but contain files like Excel or Word documents. These files take advantage of a weakness in Microsoft Office called CVE-2017-11882, which was fixed in 2017. When someone opens these files, they unknowingly download a Visual Basic Script (VBS) from a source that seems real. This script then fetches an image file (JPG) that hides a secret payload encoded in base64 format.
Diverse Malware Payloads
The hidden payload serves as a gateway to various malware families, each with distinct functionalities:
1. AgentTesla: A spyware capable of keylogging, credential theft, and capturing screenshots.
2. FormBook: An infostealer malware adept at harvesting credentials, monitoring keystrokes, and executing downloaded files.
3. Remcos: A remote access tool enabling attackers to manage compromised machines remotely, including activating webcams and microphones.
4. LokiBot: Another infostealer focusing on extracting sensitive information from commonly used applications.
5. Guloader: It serves as a downloader in cyberattacks, distributing secondary payloads to evade antivirus detection.
6. Snake Keylogger: Snake Keylogger is malware designed to steal data by logging keystrokes, capturing screenshots, and harvesting credentials from web browsers.
7. XWorm : It functions as a Remote Access Trojan (RAT), granting attackers remote control over compromised computers for executing commands and accessing sensitive information.
To evade detection, the final payloads and malicious scripts are often stored in reputable cloud services like Google Drive. Additionally, stolen data is transmitted to compromised FTP servers, masquerading as normal traffic.
Protective Measures
Despite the complexity of the attack, safeguarding against SteganoAmor is relatively straightforward. Updating Microsoft Office to the latest version eliminates the vulnerability exploited by the attackers, rendering their tactics ineffective.
Global Impact
While the primary targets seem concentrated in Latin America, the reach of SteganoAmor extends worldwide, posing a significant threat to organisations globally.
As these threats are taking new shape and form, staying aware and implementing timely updates remain crucial defences against cyber threats of any capacity.
X, the social media platform formerly known as Twitter, recently grappled with a significant security flaw within its iOS app. The issue involved an automatic alteration of Twitter.com links to X.com links within Xeets, causing widespread concern among users. While the intention behind this change was to maintain brand consistency, the execution resulted in potential security vulnerabilities.
The flaw originated from a feature that indiscriminately replaced any instance of "Twitter" in a URL with "X," regardless of its context. This meant that legitimate URLs containing the word "Twitter" were also affected, leading to situations where users unknowingly promoted malicious websites. For example, a seemingly harmless link like netflitwitter[.]com would be displayed as Netflix.com but actually redirect users to a potentially harmful site.
The implications of this flaw were significant, as it could have facilitated phishing campaigns or distributed malware under the guise of reputable brands such as Netflix or Roblox. Despite the severity of the issue, X chose not to address it publicly, likely in an attempt to mitigate negative attention.
The glitch persisted for at least nine hours, possibly longer, before it was eventually rectified. Subsequent tests confirmed that URLs are now displaying correctly, indicating that the issue has been resolved. However, it's important to note that the auto-change policy does not apply when the domain is written in all caps.
This incident underscores the importance of thorough testing and quality assurance in software development, particularly for platforms with large user bases. It serves as a reminder for users to exercise caution when clicking on links, even if they appear to be from trusted sources.
To better understand how platforms like X operate and maintain user trust, it's essential to consider the broader context of content personalization. Profiles on X are utilised to tailor content presentation, potentially reordering material to better match individual interests. This customization considers users' activity across various platforms, reflecting their interests and characteristics. While content personalization enhances user experience, incidents like the recent security flaw highlight the importance of balancing personalization with user privacy and security concerns.
