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 Exploit ThinkPHP and ownCloud Vulnerabilities from 2022 and 2023

 

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.
