Hackers just leaked 19,000 files tied to India's largest nuclear plant.
Kudankulam. The crown jewel of the country's atomic energy plans.
And now, anti-nuclear activists are demanding the government explain exactly how it happened.
Here's what we know so far.
A ransomware group called World Leaks claims responsibility.
The breach traces back to a server run by Reliance Group, one of the plant's contractors — hosted on third-party data centre Yotta.
Reliance has confirmed a "partial breach."
The government has been informed.
What's reportedly inside those files:
The good news? The core reactor systems — built by Russia's Rosatom — don't appear to be exposed.
The bad news? Everything else could still help someone map the plant's weak points.
S P Udayakumar, who leads the National Alliance of Anti-nuclear Movements, isn't just asking for a probe.
He's asking why India still leans on nuclear at all.
👉 It supplies barely 3% of the national grid.
His demand: investigate the leak, halt privatisation, and start phasing nuclear out entirely.
Chennai-based Poovulagin Nanbargal went further — urging the Tamil Nadu government to march straight to the Centre for answers.
Just two months ago, in May 2026, the Delhi High Court ruled that Kudankulam's safety analysis report was exempt from RTI disclosure.
Too sensitive for citizens to see.
Yet a ransomware gang apparently got it anyway.
The public was locked out through the front door.
A hacker walked in through the back.
That's the story unsettling people right now — not just what leaked, but how easily it did.
That's all for now!
