According to an international news agency, the ransomware group World Leaks has claimed responsibility for publishing thousands of documents related to the Kudankulam Nuclear Power Plant on the dark web.
The leaked files reportedly include maps of certain sections of the facility, supplier information, inspection and meeting records, equipment assessments, and insurance-related documents.
Located in the southern state of Tamil Nadu, the Kudankulam Nuclear Power Plant is India s largest nuclear power station and is considered a key part of Prime Minister Narendra Modi s plan to expand the country s nuclear energy capacity.
Reliance Group, which is involved in construction projects linked to the plant, confirmed that unauthorized access had been gained to some of its data stored on the server of a third-party information center. The company said it had informed the government about the incident but did not specify what data had been affected.
An independent cybersecurity expert said approximately 19,000 files, totaling 14.3 GB, have been available on the dark web for several weeks. The news agency reviewed the documents but said it could not independently verify their authenticity.
Meanwhile, the Nuclear Power Corporation of India (NPCIL) stated that the leaked information relates only to general services and has no connection with the plant s nuclear safety or security systems. The corporation said there is no cause for public concern.
India s national cybersecurity agency is investigating the incident. Experts say claims involving leaked information from critical infrastructure highlight the growing threat of cyberattacks and underscore the need for stronger cybersecurity measures to protect sensitive facilities.
