NPCIL cyber attack explained: What was leaked in the Kudankulam data…

Ransomware group World Leaks breached Reliance Infrastructure's servers, exposing ~19,000 files (14.3 GB) containing engineering drawings, vendor lists, and operational documents from India's Kudankulam Nuclear Power Plant Units 3 and 4. NPCIL confirms no reactor safety systems were compromised, but experts warn that infrastructure and supply-chain data could expose facility vulnerabilities to targeted attacks. If you supply components, services or infrastructure to nuclear or defence facilities, your customer's security posture is now your liability. A breach of their EPC contractor just exposed your company name, your contract terms, and your facility layouts to threat actors mapping supply chains.
