'Serious risk' to India's largest nuclear plant after sensitive files leaked on dark web: Report

A ransomware group named World Leaks published over 19,000 files allegedly linked to India's Kudankulam Nuclear Power Plant on the dark web.

The files are part of a larger cache of approximately 858,000 files allegedly stolen from Reliance Group, a contractor for the plant.

Reliance Group confirmed a partial breach of data on a server hosted by Indian data centre provider Yotta, and the government has been informed.

Leaked documents include engineering blueprints for ventilation and cooling systems, floor layouts of a common control room, and supplier lists for Units 3 and 4.

Experts warn the leak could pose a serious security risk, potentially revealing system access points to adversaries, though no core reactor designs were compromised.
