The Russian-linked LockBit ransomware gang has claimed responsibility for the Royal Mail cyberattack and is threatening to publish the data it stole from the U.K. postal giant.
Royal Mail, which has been battling a cyberattack since January 10, was added to LockBit’s dark web leak site on Monday. The listing, seen by TechCrunch, doesn’t say how much or what types of data have been stolen from Royal Mail, but LockBit is threatening to publish “all available data” on February 9. This suggests that the ransomware gang’s ransom demand — the amount of which remains unknown — has not been paid.
