Kudankulam nuclear plant data leak sparks ‘absolute commotion’
The leak of highly sensitive files of Kudankulam Nuclear Power Plant (KKNPP), reportedly accessed by a ransomware group from a contractor’s server, has triggered absolute commotion in the plant, KKNPP sources said on Wednesday.After commissioning two 1,000 Mwe VVER reactors, KKNPP is building four more such units with Russian collaboration.
Sources said the top brass of the upcoming nuclear park is completely clueless about the development that poses a security threat as it may let an adversary map the support system and identify vulnerabilities.
According to Reuters, more than 19,000 files dating between 2016 and mid-2025, and linked to KKNPP’s engineering blueprints on control, cooling and ventilation systems, list of vendors and suppliers, etc. had been accessed by World Leaks.
Nuclear Power Corporation of India Limited said the information claimed to be available in public domain pertains to conventional balance of plant common service facilities and does not relate to any nuclear safety or nuclear security-related systems.
The leak originated from a server hosted by third party provider Yotta. The plant’s contractor, Anil Ambani’s Reliance Group, has admitted that a partial breach had happened and the government had been informed.
Suspicious activity on Yotta’s server was noted on May 29 last and it was reported in June-end. Investigations by Nuclear Power Corporation of India Limited, the project proponent, and Computer Emergency Response Team are on, the sources said.
Reliance Group’s Reliance Infrastructure bagged the contract in 2018 to build infrastructure for rectors 3 and 4, both under construction.
When the KKNPP encountered a similar incident in 2019, wherein a North Korean malware infection on its administrative network exposed the plant’s vulnerability, NPCIL had dismissed it saying that their unbreachable standalone network was intact and no data could be accessed by any dark web.
