NPCIL says World Leaks posted Kudankulam nuclear plant files.
World Leaks says the data came from Reliance Group, with Reliance Infrastructure confirming a breach on a Yotta server.
About 19,000 files (14.3 GB) were leaked, including ventilation and cooling blueprints for Units 3-4, a control-room floor plan, supplier lists and 2024 inspection records.
An insurance policy would pay $112 million if Unit 3 or Unit 4 suffers a terrorist act, with CERT-In and NPCIL investigating.

Summary

Yotta Blocks Ransomware

Yotta blocked a ransomware attack on May 29 before attackers could claim data theft.
Reliance Group alerted the Indian government, prompting a high-level security review while CERT-In and NPCIL began a joint probe that revisits the 2019 North Korean-linked malware case at Kudankulam.
Analysts warn the leaked engineering data could help adversaries find plant support and supply-chain flaws while no Rosatom reactor design documents were stolen, limiting core technology exposure.

Summary

World Leaks Files

World Leaks released engineering and supplier files on the Kudankulam nuclear expansion after ransom demands were refused.
The Kudankulam project is a flagship component of Prime Minister Narendra Modi’s plan to double India’s nuclear power capacity.
Surfshark reported India was the world’s third-most breached nation last year, with 28.9 million compromised accounts.
An industry survey found 73 % of Indian firms are unsure of prior breaches and 57 % lack basic cyber-hygiene measures.

History

Historical Context

First uncovered on 17 June 2010, the Stuxnet worm—built in a U.S.–Israel Operation Olympic Games—targeted Siemens SCADA at Iran’s Natanz plant, infecting more than 200,000 computers and destroying up to 1,000 centrifuges. The 2024 Kudankulam breach, involving NPCIL, Reliance Group and CERT-In, revives those lessons, prompting India to harden control-system networks and seek international cooperation.
