Authorities across nine countries have taken down infrastructure linked to the KillSec ransomware group in an international operation.
Three suspects were arrested, including a 16-year-old suspected of being the group's main operator. Authorities linked KillSec to around 1,000 suspected attacks worldwide, with roughly 500 identified as successful so far.
Investigators secured at least 110 TB of stolen data and took control of five servers used by the group. Eight properties were also searched across Spain, Greece, Romania and the UK.
KillSec allegedly exploited software vulnerabilities and poorly secured access points, particularly those linked to cloud storage, before threatening victims with publication of their stolen data unless a ransom was paid.
The operation was coordinated by Europol and Eurojust.
