The Claim

The ransomware group World Leaks posted a large cache of files related to the Kudankulam Nuclear Power Plant on the dark web.

The Short Version

Reporting strongly supports that World Leaks placed a sizable set of Kudankulam-related files on the dark web. Reuters reviewed the posting and described roughly 19,000 files totaling about 14.3 GB, and other reputable outlets reported the same. The main caveat is that the files’ authenticity and sensitivity were not fully independently verified.

Caveats

  • The evidence supports that files were posted, but not that all files were authentic, sensitive, or operationally critical.
  • The material appears linked at least partly through contractor Reliance Infrastructure, so readers should not assume a direct compromise of the plant’s core systems from this claim alone.
  • Some lower-quality sources in the evidence pool are unverified and should not carry weight compared with Reuters and other established outlets.
