A ransomware group, World Leaks, has published over 19,000 sensitive files allegedly stolen from Reliance Group, a contractor involved in India’s Kudankulam Nuclear Power Plant.
The disruption is felt across the environment, affecting Server hosted by Yotta (Indian data center provider), and exposing 19,000+ sensitive files, with nearly 19,000+ records at risk.
In response, moved swiftly to contain the threat with measures like Ransomware execution halted (claimed by Yotta), and stakeholders are being briefed through Partial confirmation by Reliance Group; no public comment from Department of Atomic Energy or Prime Minister’s Office.
The case underscores how Ongoing (CERT-In, Nuclear Power Corporation of India), teams are taking away lessons such as Growing cybersecurity risks to critical infrastructure; need for stronger protections across supply chains, particularly in nuclear energy expansion, and recommending next steps like Enhance supply chain security, improve contractor cybersecurity standards, and strengthen monitoring of third-party vendors.
