Ransomware group World Leaks has posted 19,000 files allegedly from Reliance Group relating to India's Kudankulam nuclear power plant, including purported blueprints of ventilation and cooling systems, supplier lists, and control room layouts. The breach, which occurred on a third-party data centre server, exposes critical infrastructure details that could help adversaries map support systems and identify security vulnerabilities.
This Wire brief sits within Fusion42's coverage of Cybersecurity.
◆ ◆ The Wire takeaway
If you supply ventilation, cooling, control systems or components to Indian nuclear or critical infrastructure projects, your customer relationships and technical specs are now on the dark web — and World Leaks typically publishes supplier lists alongside blueprints. You need to call your nuclear customers this week to confirm whether your designs or contract terms were in those 19,000 files.
