Claims of India's nuclear files appearing on the dark web have raised security concerns. Here's what is known so far, the official response, and the latest updates. Reliance Group admits partial breach: Report
New Delhi: A large number of files allegedly from India's largest nuclear plant, the Kudankulam Nuclear Power Plant (KNPP), have been leaked on the dark web. This has sparked concerns potentially sensitive information reaching the wrong hands, as the Tamil Nadu-based power plant is central to the Prime Minister Narendra Modi government's atomic energy plans.
Developed jointly with Russia, the nuclear plant uses VVER-1000 Light Water Reactors, which have higher power caps than the indigenous Pressurised Heavy Water Reactors (PHWRs), allowing for more output.
While two of its units, producing 1000 megawatts (MW) each are currently operational, four more such units will be completed by 2027, of which the first two will be built by Reliance Group subsidiary Reliance Infrastructure.
8,58,000 files were posted on the dark web by ransomware group World Leaks, which it claimed were from the Reliance Group, a Reuters report said.
19,000 of these files appeared to be highly sensitive, the report added, noting that the documents were dated between 2016 and 2025, and reportedly featured blueprints, supplier details, meeting and inspection records, equipment reviews and insurance policies.
It is also alleged that World Leaks may have been denied a ransom payment, as it usually first uses the corporate data as ransom to try obtaining huge sums of money to prevent the leak. The Reliance Group admitted to Reuters that a "partial breach" of its data had taken place from a server hosted by Yotta, a third-party Indian data centre service provider, and that the government has been informed the incident.
