Kudankulam data leak

Prelims and Mains

The Kudankulam plant is India's largest nuclear power station, and the files published on it by a ransomware group came from a contractor's data held by a third party, which is the supply chain weakness typical of attacks on critical infrastructure.

What changed

15 Jul 2026New subject
- A ransomware group published about 19,000 files on the Kudankulam nuclear plant, taken from a contractor's data hosted with a third party provider and not from the plant's own network.
- The operator says the files concern the conventional balance of plant, the non nuclear support systems of Units 3 and 4, and not nuclear safety systems.
Mains: the breach came through the supply chain, which is the standard weakness of critical infrastructure.
