Files Relating to India's Largest Nuclear Plant Kudankulam Exposed in Data Breach

Sensitive files relating to the Kudankulam Nuclear Power Plant, India's largest nuclear facility, have been exposed in a data breach, according to an exclusive Reuters report. The revelation raises urgent questions about the cybersecurity posture of one of India's most strategically critical infrastructure assets.

Kudankulam, situated on the southern tip of Tamil Nadu and constructed with Russian technical and financial cooperation, is a cornerstone of India's civil nuclear power programme. The plant operates multiple reactors and contributes significantly to India's nuclear energy generation capacity. Any compromise of its operational or technical files carries serious implications for both plant safety and national security.

This is not the first time Kudankulam has faced a cybersecurity scare — the facility was previously linked to a malware incident that drew significant attention. The latest data breach, as reported by Reuters, suggests that the vulnerabilities at the plant may be deeper or more persistent than previously acknowledged. The Nuclear Power Corporation of India Limited, which operates the plant, has not immediately responded publicly to the latest report.

The incident is likely to intensify scrutiny of cybersecurity standards across India's nuclear sector and could prompt calls from Parliament and security experts for a comprehensive audit of digital defences at sensitive installations. For a country expanding its nuclear energy ambitions, protecting the digital integrity of its plants is as critical as their physical security.
