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.
