Cybercrime Group Changes Plans: Drops Ransomware, Focuses on Data Theft

 



A cybercriminal group known for ransomware attacks has decided to stop using those methods and instead focus only on stealing information and demanding money in return. The group, called Hunters International, has rebranded and is now running a new operation.

This group had earlier announced in November 2024 that it would stop its activities. They claimed it was because of low profits and growing attention from police and other authorities. But cybersecurity experts discovered that the group didn’t actually stop – they just changed their approach.

Now, under a new name, World Leaks, the group has returned. Instead of locking people’s files and asking for payment to unlock them, they now secretly steal private data from computers and threaten to release it online unless they’re paid.

According to cybersecurity researchers at Group-IB, the people working with this group are being given a special tool. This software helps them quickly and quietly copy important files from an organization’s systems. It’s believed to be a newer version of a tool they’ve used in the past.

In their earlier version, Hunters International combined two actions: they locked systems (ransomware) and demanded money, and also stole data. But now, they are only stealing data and skipping the system lockout part, which brings less risk and may be harder for authorities to detect.

Hunters International first appeared in late 2023 and was suspected to be connected to an older cyber gang called Hive. Their malware could attack many types of computer systems, including those used by businesses, governments, and servers for virtual machines.

Since then, the group has been behind over 280 attacks on organizations across the globe. They’ve gone after major companies, government bodies, hospitals, and even defense-related firms. In one serious case, they threatened to release personal health records of over 800,000 patients if they weren’t paid.

The group has been targeting companies of all sizes. Experts have seen ransom demands vary, sometimes reaching millions, depending on how large or important the organization is.

Experts say that this shift shows how cybercriminals are always changing tactics to stay ahead. With ransomware becoming riskier and less profitable, many groups may now turn to stealing data as their main method.

To stay safe, organizations should improve their security systems, watch for unusual access, and take steps to protect sensitive data before it’s too late.

ToddyCat Hackers Exploit ESET Vulnerability to Deploy Stealth Malware TCESB

 

A cyber-espionage group known as ToddyCat, believed to have ties to China, has been observed exploiting a security flaw in ESET’s software to deliver a new and previously undocumented malware strain called TCESB, according to fresh findings by cybersecurity firm Kaspersky. The flaw, tracked as CVE-2024-11859, existed in ESET’s Command Line Scanner. 

It improperly prioritized the current working directory when searching for the Windows system file “version.dll,” making it possible for attackers to substitute a malicious version of the file and gain control of the software’s behavior through a method known as DLL Search Order Hijacking. 

ESET has since released security updates in January 2025 to correct the issue, noting that attackers would still require administrative privileges to take advantage of the bug.  
Kaspersky’s research linked this technique to ToddyCat activity discovered in early 2024, where the suspicious “version.dll” file was planted in temporary directories on compromised systems. TCESB, the malware delivered via this method, had not been linked to the group before. It is engineered to evade monitoring tools and security defenses by executing payloads discreetly. 

TCESB is based on a modified version of the open-source tool EDRSandBlast, designed to tamper with low-level Windows kernel structures. It specifically targets mechanisms used by security solutions to track system events, effectively blinding them to malicious activity. To perform these actions, TCESB employs a Bring Your Own Vulnerable Driver (BYOVD) tactic, installing an outdated Dell driver (DBUtilDrv2.sys) that contains a known vulnerability (CVE-2021-36276). 

This method grants the malware elevated access to the system, enabling it to bypass protections and alter kernel processes. Similar drivers have been misused in the past, notably by other threat actors like the North Korea-linked Lazarus Group. Once the vulnerable driver is active, TCESB runs a loop that monitors for a payload file with a specific name. 

When the file appears, it is decrypted using AES-128 encryption and executed immediately. However, the payloads themselves were not recovered during analysis. Security analysts recommend that organizations remain vigilant by tracking the installation of drivers with known weaknesses and watching for kernel-level activity that shouldn’t typically occur, especially in environments not configured for debugging. The discovery further highlights ToddyCat’s ability to adapt and refine its tools. 

The group has been active since at least 2020, frequently targeting entities in the Asia-Pacific region with long-term, data-driven attacks.

Smishing Surge Expected in 2025 Driven by Sophisticated Phishing-as-a-Service Platform

Security researchers are sounding the alarm on a looming global wave of smishing attacks, warning that a powerful phishing-as-a-service (PhaaS) platform named Lucid—run by Chinese-speaking threat actors—is enabling cybercriminals to scale operations across 88 countries. 

According to threat intelligence firm Catalyst, Lucid has evolved from local-level operations into a globally disruptive tool, with a sharp increase in activity anticipated by early 2025. The platform allows attackers to send malicious links via Apple iMessage and Android’s Rich Communication Services, bypassing traditional telecom network filters. It also features a credit card validator, helping criminals confirm stolen financial information in real time. 

Lucid’s architecture offers an automated, subscription-based model that supports customizable phishing campaigns, leveraging anti-detection strategies like IP blocking, user-agent filtering, and time-limited URLs to avoid scrutiny. Threat actors using Lucid are increasingly impersonating trusted entities—such as government agencies, postal services, and toll collection services—to deceive victims and steal sensitive data. 

The U.S. has been hit particularly hard, with smishing scams prompting alerts from the FBI, FTC, state governments, and attorneys general. What sets Lucid apart is its efficiency and scale: researchers say it can send over 100,000 phishing messages per day. Its structure includes roles ranging from administrators to guest users, with weekly licensing options and automatic suspensions for non-renewal. 

These campaigns are notably effective, with a reported success rate of 5%. By operating over the internet and using device fingerprinting and geo-targeted phishing pages, Lucid boosts its reach while staying under the radar. 

It sources phone numbers through data breaches, OSINT, and darknet markets, making it one of the most sophisticated PhaaS platforms today—alongside others like Darcula and Lighthouse. As cybercriminals continue to embrace this plug-and-play model, experts fear smishing will become an even more pervasive threat in the months ahead.

Check Point Downplays Hacker’s Claims Amid Alleged Data Breach

 

A hacker using the alias “CoreInjection” has claimed responsibility for stealing what they describe as a “highly sensitive” dataset from cybersecurity firm Check Point. 
According to several media reports, the alleged stolen data includes user login credentials, employee contracts, and internal network blueprints. Despite these claims, Check Point has downplayed the incident, describing it as an outdated and isolated event involving a single account with restricted access. 

The company emphasized that no customer systems, production environments, or core security infrastructure were affected. In an official statement, Check Point clarified that the incident had occurred months ago and was addressed at the time. 

The firm criticized the hacker’s claims as misleading, suggesting they are reusing old data to create a false narrative. Cybersecurity expert Alon Gal, CTO of Hudson Rock, expressed concerns over the situation, noting that there is a strong possibility the breach involved access to a privileged administrator account—though he acknowledged that the event has yet to be fully confirmed. 

This isn’t the first time Check Point has faced such scrutiny. In 2024, its VPN software was targeted by attackers attempting to exploit it to breach corporate networks. However, those efforts were largely unsuccessful, and the company quickly issued a straightforward fix. 

While Check Point continues to reassure stakeholders that no major security risk was posed, the incident highlights the persistent threats facing even the most established cybersecurity firms.

Connor Moucka Extradited to U.S. for Snowflake Data Breaches Targeting 165 Companies

 

Connor Moucka, a Canadian citizen accused of orchestrating large-scale data breaches affecting 165 companies using Snowflake’s cloud storage services, has agreed to be extradited to the United States to face multiple federal charges. The breaches, which targeted high-profile companies like AT&T and Ticketmaster, resulted in the exposure of hundreds of millions of sensitive records. 

Moucka, also known by online aliases such as “Waifu,” “Judische,” and “Ellyel8,” was arrested in Kitchener, Ontario, on October 30, 2024, at the request of U.S. authorities. Last Friday, he signed a written agreement before the Superior Court of Justice in Kitchener, consenting to his extradition without the standard 30-day waiting period. The 26-year-old faces 20 charges in the U.S., including conspiracy to commit computer fraud, unauthorized access to protected systems, wire fraud, and aggravated identity theft. Prosecutors allege that Moucka, along with co-conspirator John Binns, extorted over $2.5 million from victims by stealing and threatening to expose their sensitive information. 

The data breaches tied to this cybercrime operation have had widespread consequences. In May 2024, Ticketmaster’s parent company, Live Nation, confirmed that data from 560 million users had been compromised and put up for sale on hacking forums. Other companies affected include Santander Bank, Advance Auto Parts, and AT&T, among others. Moucka and Binns are believed to be linked to “The Com,” a cybercriminal network involved in various illicit activities, including cyber fraud, extortion, and violent crimes. 

Another alleged associate, Cameron Wagenius, a 21-year-old U.S. Army soldier, was arrested in December for attempting to sell stolen classified information to foreign intelligence agencies. Wagenius has since indicated his intent to plead guilty. U.S. prosecutors claim Moucka and his associates launched a series of cyberattacks on Snowflake customers, gaining unauthorized access to corporate environments and exfiltrating confidential data. 
These breaches, described as among the most extensive cyberattacks in recent history, compromised sensitive 
records from numerous enterprises. While the exact date of Moucka’s extradition remains undisclosed, his case underscores the growing threat of cyber extortion and the increasing international cooperation in tackling cybercrime. His legal representatives have not yet issued a statement regarding the extradition or upcoming trial proceedings.

Oracle Denies Claim of Server Breach

 

Following a threat actor's claim to be selling 6 million data records allegedly stolen from Oracle Cloud's federated SSO login servers, Oracle denies that it was compromised. 

“There has been no breach of Oracle Cloud. The published credentials are not for the Oracle Cloud. No Oracle Cloud customers experienced a breach or lost any data," the company noted. 

This accusation follows the release of many text files yesterday by a threat actor going by the moniker rose87168, which included a sample database, LDAP details, and a list of the businesses they said were pilfered from Oracle Clouds' SSO platform.

The threat actor provided BleepingComputer with this URL as additional evidence that they were able to access Oracle Cloud servers. It displays an Internet Archive URL indicating that they submitted a.txt file to the login.us2.oraclecloud.com server that contained their ProtonMail email address.

The attackers uploaded a text file with their email address without having access to Oracle Cloud servers, as BleepingComputer explained when they got in touch with Oracle once more. 

Alleged Oracle data leak 

Rose87168 is currently offering the allegedly stolen data from Oracle Cloud's SSO service for an undisclosed fee or in exchange for zero-day exploits on the BreachForums hacking community. The information, which included enterprise manager JPS keys, Java Keystore (JKS) files, and encrypted SSO passwords, was allegedly stolen during an intrusion into Oracle servers based in 'login.(region-name).oraclecloud.com'.

"The SSO passwords are encrypted, they can be decrypted with the available files. also LDAP hashed password can be cracked," rose87168 says. "I'll list the domains of all the companies in this leak. Companies can pay a specific amount to remove their employees' information from the list before it's sold.” 

They've also promised to share part of the data with anyone who can help decrypt the SSO or LDAP credentials. The threat actor told BleepingComputer that they acquired access to Oracle Cloud servers about 40 days ago and claimed to have emailed the firm after exfiltrating data from the US2 and EM2 regions.

In the email conversation, rose87168 said that they asked Oracle to pay 100,000 XMR for information on how they infiltrated the systems, but the company allegedly refused to pay after requesting for "all information needed for fix and patch.” 

When questioned how they breached the servers, the attackers stated that all Oracle Cloud servers are running a vulnerable version with a public CVE (flaw) that does not yet have a public PoC or exploit. However, BleepingComputer was unable to independently verify whether this was the case.

Western Alliance Bank Data Breach Exposes Nearly 22,000 Customers’ Personal Information

 

Western Alliance Bank has alerted nearly 22,000 customers that their personal information was compromised following a cyberattack in October. The breach stemmed from a vulnerability in a third-party vendor’s secure file transfer software, which allowed attackers to gain unauthorized access to the bank’s systems and extract sensitive customer data. 

Western Alliance, a subsidiary of Western Alliance Bancorporation with over $80 billion in assets, first disclosed the incident in a February SEC filing. The bank revealed that hackers exploited a zero-day vulnerability in the software, which was officially disclosed on October 27, 2024. However, unauthorized access to the bank’s systems had already occurred between October 12 and October 24. The breach was only confirmed after the attackers leaked stolen files online. 

According to breach notification letters sent to 21,899 affected customers and filed with the Office of Maine’s Attorney General, the stolen data includes names, Social Security numbers, birth dates, financial account details, driver’s license numbers, tax identification numbers, and passport information if previously provided to the bank. Despite the exposure, Western Alliance stated there is no evidence of fraud or identity theft resulting from the breach. 

To support affected customers, the bank is offering one year of free identity protection services through Experian IdentityWorks Credit 3B. Although Western Alliance did not disclose the name of the compromised software in its SEC filing or customer notifications, the Clop ransomware gang has claimed responsibility for the attack. In January, Clop listed the bank among 58 companies targeted in a campaign that exploited a critical zero-day vulnerability (CVE-2024-50623) in Cleo LexiCom, VLTransfer, and Harmony software. 

The ransomware group had previously leveraged similar security flaws in MOVEit Transfer, GoAnywhere MFT, and Accellion FTA to conduct large-scale data theft operations. Further investigations revealed that Clop exploited an additional zero-day vulnerability (CVE-2024-55956) in Cleo software in December. This allowed them to deploy a Java-based backdoor, dubbed “Malichus,” enabling deeper infiltration into victims’ networks. Cleo, which serves over 4,000 organizations worldwide, confirmed the vulnerability had been used to install malicious backdoor code in affected instances of its Harmony, VLTrader, and LexiCom software. 

The full extent of the breach remains unclear, but it highlights the growing risks posed by vulnerabilities in third-party software. Organizations relying on such solutions must remain vigilant, promptly apply security patches, and implement robust defenses to prevent similar incidents.

The Growing Threat of Infostealer Malware: What You Need to Know

 

Infostealer malware is becoming one of the most alarming cybersecurity threats, silently stealing sensitive data from individuals and organizations. This type of malware operates stealthily, often going undetected for long periods while extracting valuable information such as login credentials, financial details, and personal data. As cybercriminals refine their tactics, infostealer attacks have become more frequent and sophisticated, making it crucial for users to stay informed and take preventive measures. 

A significant reason for concern is the sheer scale of data theft caused by infostealers. In 2024 alone, security firm KELA reported that infostealer malware was responsible for leaking 3.9 billion passwords and infecting over 4.3 million devices worldwide. Similarly, Huntress’ 2025 Cyber Threat Report revealed that these threats accounted for 25% of all cyberattacks in the previous year. This data highlights the growing reliance of cybercriminals on infostealers as an effective method of gathering personal and corporate information for financial gain. 

Infostealers operate by quietly collecting various forms of sensitive data. This includes login credentials, browser cookies, email conversations, banking details, and even clipboard content. Some variants incorporate keylogging capabilities to capture every keystroke a victim types, while others take screenshots or exfiltrate files. Cybercriminals often use the stolen data for identity theft, unauthorized financial transactions, and large-scale corporate breaches. Because these attacks do not immediately disrupt a victim’s system, they are harder to detect, allowing attackers to extract vast amounts of information over time. Hackers distribute infostealer malware through multiple channels, making it a widespread threat. 

Phishing emails remain one of the most common methods, tricking victims into downloading infected attachments or clicking malicious links. However, attackers also embed infostealers in pirated software, fake browser extensions, and even legitimate platforms. For example, in February 2025, a game called PirateFi was uploaded to Steam and later found to contain infostealer malware, compromising hundreds of devices before it was removed. Social media platforms, such as YouTube and LinkedIn, are also being exploited to spread malicious files disguised as helpful tools or software updates. 

Beyond stealing data, infostealers serve as an entry point for larger cyberattacks. Hackers often use stolen credentials to gain unauthorized access to corporate networks, paving the way for ransomware attacks, espionage, and large-scale financial fraud. Once inside a system, attackers can escalate their access, install additional malware, and compromise more critical assets. This makes infostealer infections not just an individual threat but a major risk to businesses and entire industries.  

The prevalence of infostealer malware is expected to grow, with attackers leveraging AI to improve phishing campaigns and developing more advanced evasion techniques. According to Check Point’s 2025 Cybersecurity Report, infostealer infections surged by 58% globally, with Europe, the Middle East, and Africa experiencing some of the highest increases. The SYS01 InfoStealer campaign, for instance, impacted millions across multiple continents, showing how widespread the issue has become. 

To mitigate the risks of infostealer malware, individuals and organizations must adopt strong security practices. This includes using reliable antivirus software, enabling multi-factor authentication (MFA), and avoiding downloads from untrusted sources. Regularly updating software and monitoring network activity can also help detect and prevent infections. Given the growing threat, cybersecurity awareness and proactive defense strategies are more important than ever.

Tata Technologies Cyberattack: Hunters International Ransomware Gang Claims Responsibility for 1.4TB Data Theft

 

Hunters International, a ransomware group known for high-profile cyberattacks, has claimed responsibility for a January 2025 cyberattack on Tata Technologies. The group alleges it stole 1.4TB of sensitive data from the company and has issued a threat to release the stolen files if its ransom demands are not met. Tata Technologies, a Pune-based global provider of engineering and digital solutions, reported the cyberattack in January. 

The company, which operates in 27 countries with over 12,500 employees, offers services across the automotive, aerospace, and industrial sectors. At the time of the breach, Tata Technologies confirmed that the attack had caused disruptions to certain IT systems but stated that client delivery services remained unaffected. The company also assured stakeholders that it was actively restoring impacted systems and conducting an internal investigation with cybersecurity experts. 

However, more than a month later, Hunters International listed Tata Technologies on its dark web extortion page, taking responsibility for the attack. The group claims to have exfiltrated 730,000 files, totaling 1.4TB of data. While the ransomware gang has threatened to publish the stolen files within a week if a ransom is not paid, it has not provided any samples or disclosed the nature of the compromised documents. Tata Technologies has yet to release an update regarding the breach or respond to the hackers’ claims. 

BleepingComputer, a cybersecurity news platform, attempted to contact the company for a statement but did not receive an immediate response. Hunters International emerged in late 2023, suspected to be a rebranded version of the Hive ransomware group. Since then, it has carried out multiple high-profile attacks, including breaches of Austal USA, a U.S. Navy contractor, and Japanese optics company Hoya. 

The group has gained notoriety for targeting various organizations without ethical restraint, even engaging in extortion schemes against individuals, such as cancer patients from Fred Hutchinson Cancer Center. Although many of the gang’s claims have been verified, some remain disputed. For example, in August 2024, the U.S. Marshals Service denied that its systems had been compromised, despite Hunters International’s assertions.  

With cybercriminals continuing to exploit vulnerabilities, the Tata Technologies breach serves as another reminder of the persistent and evolving threats posed by ransomware groups.

Sophisticated BEC Attack Exploits Business Trust to Steal Funds


A recent Business Email Compromise (BEC) investigation has uncovered a highly sophisticated attack that went beyond traditional email fraud. Instead of simply sending fraudulent emails in hopes of deceiving victims, cybercriminals strategically exploited the implicit trust between three business partners—Partner A, Partner B, and Partner C. 

By infiltrating an email server, they gained full visibility into ongoing transactions and used this access to manipulate communications and divert funds into their own accounts. The attack unfolded in two distinct phases. Initially, the threat actors gained control of a compromised third-party email server, which they used to send fraudulent messages. 

Unlike typical phishing scams, this attack was highly calculated. The attackers carefully studied the writing styles of their targets, replicating common phrases, salutations, and email footers to make their messages appear authentic. A key tactic in this attack was the gradual replacement of legitimate email recipients with addresses controlled by the attackers. 
Over time, they subtly altered the email chain by replacing the intended recipients with fake accounts while keeping email headers intact. This tricked both Partner A and Partner B into believing they were corresponding with the right individuals when, in reality, their messages were being intercepted and manipulated. The attackers also manipulated email authentication protocols to evade detection. 

By misconfiguring the third-party email server, they ensured that fraudulent emails passed Sender Policy Framework (SPF) checks, making them appear legitimate. Additionally, they altered the “Reply-To” field while maintaining the sender’s name in the “From” field, making it difficult for recipients to detect the fraud. A significant aspect of the attack was the patience and planning involved. 

When the initial fraudulent email was rejected by Partner B’s system, the attackers waited 4.5 hours before resending it, ensuring that it blended seamlessly into the conversation. As a result, when Partner B received updated wiring instructions, they assumed it was a genuine request from Partner A and proceeded with the transfer. 

The scam was only discovered when Partner A followed up for payment confirmation—12 days after the initial invoice reminder. By then, the funds had already been moved, making recovery nearly impossible. This case underscores the evolving complexity of BEC scams, highlighting the urgent need for stronger cybersecurity measures and awareness training to prevent such costly attacks.

Qilin Ransomware Outfit Claims Credit for Lee Enterprises Breach

 

The Lee Enterprises attack that caused disruptions on February 3 has been linked to the Qilin ransomware group, which has released samples of data they claim were stolen from the enterprise. The ransomware actors have now threatened to release all of the allegedly stolen material unless a ransom demand is fulfilled.

The US-based media firm Lee Enterprises owns and runs 350 magazines, 77 daily newspapers, digital media platforms, and marketing services. The company's internet viewership reaches tens of millions each month, and its main concentration is local news and advertising.

In a report with the Securities and Exchange Commission (SEC) earlier this month, the company disclosed that it was subjected to a cyberattack on February 3, 2025, resulting in major operational disruption. Threat analysts discovered that the outage created serious issues, including lost access to internal systems and cloud storage, as well as non-functioning corporate VPNs.

A week later, Lee Enterprises filed a new statement with the SEC, stating that the attackers "encrypted critical applications and exfiltrated certain files," implying that they had been targeted by ransomware. 

Earlier this week, Qilin ransomware added Lee Enterprises to its dark web extortion site, publishing samples of allegedly stolen data such as government ID scans, non-disclosure agreements, financial spreadsheets, contracts/agreements, and other private papers reportedly stolen from the company. 

Evolution of Qilin ransomware

Despite not being one of the most active ransomware groups, Qilin has advanced significantly since being introduced in August 2022 under the alias "Agenda.”

In the years that followed, the cybercriminals claimed hundreds of victims, with prominent examples including automotive manufacturer Yangfeng, Australia's Court Services Victoria, and many major NHS hospitals in London. 

In terms of technical evolution, Qilin delivered a Linux (VMware ESXi) variation in December 2023, began deploying a custom Chrome credentials stealer in August 2024, and launched a Rust-based data locker with stronger encryption and better evasion in October. 

Microsoft released a report last year claiming that the infamous members of the hacking group known as "Scattered Spider" had started using the Qilin ransomware in their attacks.

U.S. Soldier Who Hacked AT&T and Verizon Sought to Sell Stolen Data to Foreign Intelligence, Prosecutors Say


A U.S. soldier who pleaded guilty to hacking AT&T and Verizon attempted to sell stolen data to what he believed was a foreign military intelligence service, according to newly filed court records reviewed by Media. 

The documents also reveal that the soldier, Cameron John Wagenius, searched online for “U.S. military personnel defecting to Russia” and “can hacking be treason.” Wagenius, who operated under the online aliases “kiberphant0m” and “cyb3rph4nt0m,” unlawfully obtained and transferred confidential phone records, including those of high-ranking public officials. 

Prosecutors allege that he posted these records for sale in November 2024 and demanded $500,000 from AT&T in exchange for deleting the stolen information, all while on active duty at Fort Cavazos. His activities were part of a larger cyberattack against multiple Snowflake customers during the summer of 2024, impacting at least ten organizations, including Live Nation Entertainment Inc. and Advance Auto Parts Inc. 

Court documents state that hackers linked to the AT&T breach targeted records associated with prominent figures, including former First Lady Melania Trump, Ivanka Trump, Vice President Kamala Harris, and the wife of Senator Marco Rubio. However, it remains unclear what specific data Wagenius attempted to sell to the foreign intelligence service.  
Prosecutors have described the extortion attempt as “only a small part of Wagenius’ malicious activity.” According to a government memorandum filed Wednesday, Wagenius allegedly communicated with an email address he believed was linked to a foreign intelligence agency and, days later, searched for information about countries that do not extradite to the U.S. 

The memorandum states, “Wagenius conducted online searches about how to defect to countries that do not extradite to the United States and that he previously attempted to sell hacked information to at least one foreign intelligence service.” Authorities have also uncovered thousands of stolen identification documents, including passports and driver’s licenses, on Wagenius’ devices, along with access to large amounts of cryptocurrency. 

Additionally, he researched the Russian embassy in Washington, D.C., raising further concerns about his intentions. Wagenius’ co-conspirator, Connor Moucka, a Canadian citizen, is set to face an extradition hearing in Canada on charges of stealing AT&T and Snowflake customer data. Another alleged accomplice, John Binns, an American living in Turkey, was reportedly fearful of being tracked by U.S. intelligence agencies. 

The extensive hacking operation, which prosecutors say resulted in millions of dollars in ransom payments, has prompted warnings from the FBI about potential risks to national security. The agency has cautioned that the breach could compromise communications between FBI agents and confidential sources.

DM Clinical Research Database Exposed Online, Leaking 1.6M Patient Records

 

A clinical research database containing over 1.6 million patient records was discovered publicly accessible online without encryption or password protection. Security researcher Jeremiah Fowler found the dataset, linked to DM Clinical Research, exposing sensitive information such as names, medical histories, phone numbers, email addresses, medications, and health conditions. 

The unprotected database, totaling 2TB of data, put those affected at risk of identity theft, fraud, and social engineering scams. While the database name suggests it belongs to DM Clinical Research, it remains unclear whether the firm directly managed it or if a third party was responsible. Fowler immediately sent a disclosure notice, and the database was taken offline within hours. 

However, it is unknown how long it remained exposed or whether threat actors accessed the data before its removal. Only a thorough forensic audit can determine the extent of the breach. DM Clinical Research responded to the disclosure, stating that they are reviewing the findings to ensure a swift resolution. They emphasized their commitment to data security and compliance with legal regulations, highlighting the importance of protecting sensitive patient information. 

However, this incident underscores the growing risks facing the healthcare industry, which remains a prime target for cyberattacks, including ransomware and data breaches. Healthcare data is among the most valuable for cybercriminals, as it contains detailed personal and medical information that cannot be easily changed, unlike financial data. 

In recent years, hackers have aggressively targeted medical institutions. In 2024, a cyberattack compromised the records of 190 million Americans, and UnitedHealth suffered a ransomware attack that leaked customer information onto the dark web. The exposure of sensitive medical conditions—such as psychiatric disorders, HIV status, or cancer—could lead to discrimination, scams, or blackmail. Attackers often use exposed medical data to craft convincing social engineering scams, posing as doctors, insurance companies, or medical professionals to manipulate victims. 

Fowler warns that health records, unlike financial data, remain relevant for a lifetime, making breaches particularly dangerous. Organizations handling sensitive data must take proactive measures to protect their systems. Encryption is critical to safeguarding customer information, as unprotected datasets could lead to legal consequences and financial losses. Real-time threat detection, such as endpoint security software, helps identify intrusions and suspicious activity before damage is done. 

In the event of a breach, transparency is essential to maintaining consumer trust and mitigating reputational harm. For individuals affected by data breaches, vigilance is key. Regularly monitoring financial accounts and bank statements for suspicious transactions can help detect fraudulent activity early. Social engineering attacks are also a major risk, as scammers may exploit exposed medical data to impersonate trusted professionals. 

Be cautious of unexpected emails, phone calls, or messages requesting personal information, and avoid opening attachments from unfamiliar sources. Using strong, unique passwords—especially for financial and healthcare accounts—adds an extra layer of security. 

This breach is yet another reminder of the urgent need for stronger cybersecurity measures in the healthcare sector. As cybercriminals continue to exploit vulnerabilities, both organizations and individuals must remain proactive in safeguarding sensitive data.

Italian Spyware Firm SIO Linked to Malicious Android Apps Targeting WhatsApp Users

 

SIO, an Italian spyware company known for selling surveillance tools to government agencies, has been linked to a series of malicious Android apps designed to mimic WhatsApp and other popular services while secretly stealing private data, TechCrunch has revealed. Late last year, a security researcher provided TechCrunch with three Android apps, alleging they were government spyware used in Italy. 

Upon investigation, Google and cybersecurity firm Lookout confirmed that these apps were indeed spyware. This discovery highlights the expanding landscape of government surveillance, with numerous companies employing varied methods to target individuals. Italy is already embroiled in a separate spyware scandal involving Israeli firm Paragon, whose sophisticated surveillance tool allegedly targeted journalists and NGO founders. 

In contrast, the SIO-linked spyware campaign relied on a more straightforward approach—disguising malicious Android apps as well-known communication and customer service applications. Lookout researchers identified the malware as Spyrtacus, a spyware capable of stealing text messages, chats from WhatsApp, Signal, and Facebook Messenger, recording calls, capturing ambient audio and camera images, and extracting contact information. 

Their analysis confirmed that SIO was responsible for creating and distributing Spyrtacus, with samples dating back to 2019. Some variants impersonated apps from Italian telecom providers TIM, Vodafone, and WINDTRE. Google stated that none of the infected apps were available on the Play Store, asserting that Android security measures have protected users from this malware since 2022. 

However, a 2024 Kaspersky report suggested that earlier versions of Spyrtacus were distributed via Google Play in 2018 before shifting to fake websites mimicking major Italian internet providers. Italy has a long history of government spyware development, with companies such as Hacking Team, Cy4Gate, and RCS Lab selling surveillance tools to international law enforcement agencies. Spyrtacus is the latest example of this trend, with Lookout identifying command-and-control servers registered to ASIGINT, an SIO subsidiary specializing in wiretapping software. 

The SIO, Italian government and the Ministry of Justice have reportedly declined to comment. Lookout has also discovered references to Naples in the malware’s source code, suggesting a possible connection to developers from the region.

Hackers are increasingly exploiting outdated security flaws in poorly maintained systems, with vulnerabilities from 2022 and 2023 seeing a surge in attacks. According to threat intelligence platform GreyNoise, malicious actors are actively targeting CVE-2022-47945 and CVE-2023-49103, affecting the ThinkPHP Framework and the open-source ownCloud file-sharing solution. 

Both vulnerabilities are critical, allowing attackers to execute arbitrary commands or steal sensitive data, such as admin credentials and license keys. CVE-2022-47945 is a local file inclusion (LFI) flaw in ThinkPHP versions before 6.0.14. If the language pack feature is enabled, unauthenticated attackers can remotely execute operating system commands. 

Akamai reported that Chinese threat groups have exploited this flaw since late 2023, and GreyNoise recently detected 572 unique IPs actively attacking vulnerable systems. Despite having a low Exploit Prediction Scoring System (EPSS) rating of just 7% and not being listed in CISA’s Known Exploited Vulnerabilities (KEV) catalog, CVE-2022-47945 remains under heavy assault. 

The second vulnerability, CVE-2023-49103, impacts ownCloud’s file-sharing software. It stems from a third-party library that leaks PHP environment details through a public URL. After its disclosure in November 2023, hackers began exploiting the flaw to steal sensitive data. A year later, it was named one of the FBI, CISA, and NSA’s top 15 most exploited vulnerabilities. 

Even though a patch was released over two years ago, many ownCloud systems remain unpatched and exposed. GreyNoise recently observed malicious activity from 484 unique IPs targeting this vulnerability. To defend against these active threats, users are strongly advised to upgrade to ThinkPHP 6.0.14 or later and ownCloud GraphAPI 0.3.1 or newer. 

Taking vulnerable systems offline or placing them behind a firewall can significantly reduce the attack surface and prevent exploitation. As hackers continue to leverage older, unpatched vulnerabilities, staying vigilant with timely updates and robust security practices remains crucial in protecting critical systems and sensitive data.

Ransomware Tactics Evolve as Hackers Shift Focus to Data Theft

 

Ransomware groups are adapting their strategies to outsmart stronger cybersecurity defenses and increasing law enforcement pressure, according to the Huntress 2025 Cyber Threat Report. The findings reveal that attackers are moving beyond traditional encryption-based ransomware, instead focusing on data theft and extortion to bypass modern protections. 

In 2024, 75% of ransomware cases Huntress investigated involved remote access Trojans (RATs), allowing hackers to infiltrate systems discreetly. Additionally, 17.3% of incidents featured the misuse of legitimate remote management tools such as ConnectWise ScreenConnect, TeamViewer, and LogMeIn. This shift reflects a growing reliance on “living off the land” techniques, where attackers use trusted administrative tools to avoid detection. 

A significant trend noted in the report is that sophisticated tactics once reserved for targeting large enterprises are now common across businesses of all sizes. Huntress observed that cybercriminals are increasingly disabling or tampering with security software to maintain access and avoid detection, effectively closing the gap between attacks on major corporations and smaller organizations.  

Huntress’ analysis of over 3 million endpoints also revealed that nearly 24% of ransomware incidents in 2024 involved infostealer malware, while malicious scripts designed to automate attacks and evade security tools appeared in 22% of cases. Greg Linares, principal threat intelligence analyst at Huntress, states that ransomware groups must constantly evolve to survive in the competitive cybercrime landscape.

“If malware isn’t staying ahead of detection techniques, it becomes obsolete fast,” Linares explained. Another key insight from the report was the speed of modern ransomware campaigns. On average, the time from initial access to the delivery of a ransom demand — known as time-to-ransom (TTR) — was just 17 hours. Some groups, including Play, Akira, and Dharma/Crysis, were even faster, with TTRs averaging around six hours.  

Interestingly, Huntress noted a clear shift in ransomware tactics: rather than encrypting data, many attackers now opt to exfiltrate sensitive information and threaten to leak it unless a ransom is paid. This change is seen as a direct response to stronger ransomware defenses and increased law enforcement efforts, which led to the takedown of major groups like Lockbit. 

However, this shift presents new challenges for companies. While endpoint detection and ransomware protections have improved, the report points out that data loss prevention (DLP) measures remain underdeveloped. Linares noted that DLP solutions are often overlooked, especially in organizations with remote work and bring-your-own-device (BYOD) policies. These environments, he said, often lack the comprehensive monitoring and control needed to prevent data exfiltration. 

To stay ahead of these evolving threats, Huntress recommends that businesses not only strengthen their ransomware defenses but also implement more robust DLP strategies to protect sensitive data. As ransomware gangs continue to adapt, companies must be proactive in addressing both encryption and data theft risks.

Malware Attack
Chrome Cyber Attacks Cyble Cyble research data security Data Theft Google Chrome security Malware Attack

Sophisticated Malware Bypasses Chrome App-Bound Encryption Using Dual Injection

 

Researchers at Cyble have identified a highly advanced malware attack that successfully bypasses Google Chrome’s App-Bound Encryption. This security feature was designed to prevent infostealer malware from accessing user data, particularly cookies. 

However, the newly discovered malware employs dual injection techniques to circumvent these defenses, allowing cybercriminals to extract sensitive credentials. The attack begins with a deceptive file distribution method. The malware is embedded within a ZIP file disguised as a PDF document. 

When opened, it executes a malicious LNK shortcut file that creates a scheduled task, running every 15 minutes. Another component of the attack is an XML project file, which is designed to appear as a PNG image, further tricking users into engaging with the malicious content.  

To execute its payload, the malware exploits MSBuild.exe, a legitimate Microsoft development tool. This enables it to run directly in system memory without creating detectable files on the disk, making it much harder for traditional security solutions to identify and stop the attack. The use of fileless execution techniques ensures that the malware operates stealthily while maintaining persistence on an infected system. 

A key aspect of this attack is its dual injection approach. The malware employs both Process Injection and Reflective DLL Injection to execute malicious code within legitimate system processes. This method allows it to blend in with normal activity while avoiding detection. By targeting Chrome’s security framework, the malware can extract encrypted login data, cookies, and other sensitive browser-stored information. 

The malware also leverages the Telegram Web API for command and control communications. This connection enables threat actors to issue remote commands, modify bot configurations, and control infected systems with minimal interference. The dynamic bot ID switching feature adds an additional layer of stealth, ensuring continued access even if parts of the attack infrastructure are disrupted. Cyble researchers noted that the malware appears to be specifically targeting organizations in Vietnam, particularly those in the telemarketing and sales industries.

However, the method it uses could be adapted for broader campaigns, posing a risk to businesses and individuals globally. The initial infection method remains unclear, but it likely involves phishing emails or malicious downloads.  

To mitigate the risk of such attacks, Cyble recommends implementing strict email attachment filtering, restricting the execution of unverified files, and enhancing user awareness about phishing threats. 

Organizations should also deploy advanced security solutions capable of detecting fileless malware attacks. The research highlights the evolving nature of cyber threats and the need for proactive cybersecurity measures to safeguard sensitive data.

Massive Mobile Malware Campaign Targets Indian Banks, Steals Financial Data

 

Zimperium's zLabs research team has uncovered a significant mobile malware campaign that targets Indian banks. First reported on February 5, 2025, this threat was orchestrated by a threat actor called FatBoyPanel. Nearly 900 malware samples are used in the campaign, which is distributed via WhatsApp and uses malicious apps that impersonate banking or government apps to steal private and sensitive financial data from unsuspecting users.  

Once installed, the malicious apps steal the users data, such as credit and debit card information, ATM PINs, Aadhaar card details, PAN card numbers, and mobile banking information. Additionally, the malware uses sophisticated stealth techniques to conceal itself and avoid detection or removal by intercepting SMS messages that contain OTPs. 

By using the reputation and legitimacy of Indian banks and government agencies to trick users into thinking the apps are authentic, this cyberattack is a clear illustration of how threat actors have advanced to a new level. These cybercriminals are deceiving users into downloading malicious apps intended to drain accounts and compromise sensitive data by posing as trustworthy organizations. 

Upon closer examination, the malware can be divided into three different types: hybrid, firebase-exfiltration, and SMS forwarding. Different exfiltration techniques are used by each variant to steal confidential information. By employing live phone numbers to intercept and reroute SMS messages in real time, these Trojan Bankers go beyond standard attacks. By hiding its icon, the malware makes itself even more difficult to remove. 

According to a Zimperium report, more than 1,000 malicious applications were created with the intention of stealing banking credentials. An estimated 50,000 victims were impacted by the campaign, which revealed 2.5GB of financial and personal data kept in 222 unprotected Firebase buckets. Attackers have been able to trick users into divulging extremely sensitive information by using phony government and banking apps that are distributed via WhatsApp. 

This breach has serious repercussions, including the possibility of identity theft, financial loss, and privacy violations for impacted users. In order to assist authorities in locating the cybercriminals responsible for FatBoyPanel, Zimperium has shared the gathered data with them. Users should use security software to identify and eliminate malware, update their devices frequently, and refrain from downloading apps from unidentified sources in order to protect themselves. 

On Thursday, Feb. 20, Zimperium, the global leader in mobile security, will release new research highlighting the evolving landscape of mobile phishing attacks.

As organizations increasingly rely on mobile devices for business operations including BYOD, multi-factor authentication, cloud applications, and mobile-first workflows, mobile phishing is becoming one of the most severe threats to enterprise security. Adversaries are exploiting security gaps in mobile and cloud-based business applications, expanding the attack surface and increasing exposure to credential theft and data compromise.

Zimperium’s latest research provides a data-driven look at how attackers are evolving their tactics to evade detection and why businesses must rethink their security strategies to stay ahead. 

Key findings from the report include: Mishing surge: Activity peaked in August 2024, with over 1,000 daily attack records. Smishing (SMS/text based phishing) attacks dominate globally with 37% in India, 16% in the U.S., and 9% in Brazil. Quishing (QR code phishing) is gaining traction, with notable activity in Japan (17%), the U.S. (15%), and India (11%). Stealthy phishing techniques: 3% of phishing sites use device-specific detection to display harmless content on desktops while delivering malicious phishing payloads exclusively to mobile users. Zimperium’s research emphasizes that traditional anti-phishing solutions designed for desktops are proving inadequate against this shift, making mobile threat defense a critical necessity for organizations worldwide.

The FatBoyPanel campaign emphasizes the need for increased vigilance in an increasingly digital world and the increasing sophistication of cyber threats. Keeping up with online security best practices is crucial to reducing risks and protecting financial and personal information as cybercriminals improve their tactics.

Amazon Faces Lawsuit Over Alleged Secret Collection and Sale of User Location Data

 

A new class action lawsuit accuses Amazon of secretly gathering and monetizing location data from millions of California residents without their consent. The legal complaint, filed in a U.S. District Court, alleges that Amazon used its Amazon Ads software development kit (SDK) to extract sensitive geolocation information from mobile apps. According to the lawsuit, plaintiff Felix Kolotinsky of San Mateo claims 

Amazon embedded its SDK into numerous mobile applications, allowing the company to collect precise, timestamped location details. Users were reportedly unaware that their movements were being tracked and stored. Kolotinsky states that his own data was accessed through the widely used “Speedtest by Ookla” app. The lawsuit contends that Amazon’s data collection practices could reveal personal details such as users’ home addresses, workplaces, shopping habits, and frequented locations. 

It also raises concerns that this data might expose sensitive aspects of users’ lives, including religious practices, medical visits, and sexual orientation. Furthermore, the complaint alleges that Amazon leveraged this information to build detailed consumer profiles for targeted advertising, violating California’s privacy and computer access laws. This case is part of a broader legal pushback against tech companies and data brokers accused of misusing location tracking technologies. 

In a similar instance, the state of Texas recently filed a lawsuit against Allstate, alleging the insurance company monitored drivers’ locations via mobile SDKs and sold the data to other insurers. Another legal challenge in 2024 targeted Twilio, claiming its SDK unlawfully harvested private user data. Amazon has faced multiple privacy-related controversies in recent years. In 2020, it terminated several employees for leaking customer data, including email addresses and phone numbers, to third parties. 

More recently, in June 2023, Amazon agreed to a $31 million settlement over privacy violations tied to its Alexa voice assistant and Ring doorbell products. That lawsuit accused the company of storing children’s voice recordings indefinitely and using them to refine its artificial intelligence, breaching federal child privacy laws. 

Amazon has not yet issued a response to the latest allegations. The lawsuit, Kolotinsky v. Amazon.com Inc., seeks compensation for affected California residents and calls for an end to the company’s alleged unauthorized data collection practices.

browser hijacking Chrome Extension Cyber Security Cybersecurity Data Theft Google Workspace Hacking phishing Security Breach

New 'Browser Syncjacking' Attack Exploits Chrome Extensions for Full Device Takeover

 

'Browser Syncjacking,' which allows threat actors to hijack Google profiles, compromise browsers, and eventually gain full control over a victim's device—all through a seemingly harmless Chrome extension.

This stealthy multi-stage attack requires minimal permissions and almost no user interaction beyond installing a malicious Chrome extension. The attack begins with:

1. Fake Google Workspace Setup – Attackers create a fraudulent Google Workspace domain with pre-configured user profiles where security features like multi-factor authentication are disabled.

2. Publishing a Malicious Extension – A Chrome extension, disguised as a useful tool, is uploaded to the Chrome Web Store.

3. Social Engineering Trap – Victims are tricked into installing the extension, which then secretly logs them into an attacker's managed Google Workspace profile via a hidden browser session.

4. Sync Activation – The extension opens a legitimate Google support page and injects content instructing users to enable Chrome Sync. Once activated, attackers gain access to stored credentials, browsing history, and other sensitive data.

5. Full Browser Takeover – Using deceptive tactics, such as a fake Zoom update prompt, the extension delivers an executable file containing an enrollment token. This grants attackers full control over the browser.

"Once enrolled, the attacker gains full control over the victim's browser, allowing them to silently access all web apps, install additional malicious extensions, redirect users to phishing sites, monitor/modify file downloads, and many more," explains SquareX researchers.

By leveraging Chrome's Native Messaging API, attackers establish a direct communication channel between the malicious extension and the victim's operating system. This enables them to:
  • Browse directories
  • Modify files
  • Install malware
  • Execute commands
  • Capture keystrokes
  • Extract sensitive data
  • Activate the webcam and microphone
The Browser Syncjacking attack is difficult to detect. Unlike traditional extension-based threats that require extensive social engineering, this method operates with minimal user interaction.

"Unless the victim is extremely security paranoid and is technically savvy enough to constantly navigate the Chrome settings to look for managed browser labels, there is no real visual indication that a browser has been hijacked," the report warns.

Recent incidents, including hijacks of legitimate Chrome extensions, have demonstrated that browser extensions pose significant cybersecurity risks.

BleepingComputer has reached out to Google for comments on this new attack and will provide updates as soon as a response is received.
