A reported cyber breach at Kudankulam Nuclear Power Plant has raised concern because more than 19,000 files were allegedly accessed from a contractor’s server by a ransomware group. The incident matters for UPSC because it links critical infrastructure, cyber security, and vendor risk in one case.

Nuclear Power Corporation of India Limited (NPCIL) said the material involved was public-domain information related to conventional support systems and not nuclear safety or security systems. NPCIL and Computer Emergency Response Team-India (CERT-In) are investigating the breach.

What happened

The files reportedly covered engineering blueprints, control, cooling and ventilation systems, vendor details, and other operational material. Senior plant officials were not immediately available for comment.
