Experts warn that the exposure of blueprints and supplier details poses a significant security risk to the facility.
Why it matters
This breach highlights critical vulnerabilities in industrial cybersecurity and the potential risks to national infrastructure.
Ransomware group ‘World Leaks’ has posted on the dark web a huge cache of files related to Kudankulam nuclear power plant, India’s largest, including purported blueprints of parts of its facilities and supplier details — information it labelled as coming from Reliance Group.
The Kudankulam nuclear power plant, located in Tamil Nadu, is the largest of India’s seven nuclear plants and central to Prime Minister Narendra Modi’s ambitious plans to expand the country’s atomic energy capacity.
Businessman Anil Ambani’s Reliance Group, one of the plant’s contractors, told Reuters in a statement that there had been a “partial breach” of its data on a server hosted by third-party Indian data centre service provider Yotta, and that the government has been informed about the incident.
Reliance did not disclose what data had been breached.
