Clop ransomware group
Clop is one of the extortion operations we watch continuously. This page covers what is known about the group and the current state of its leak site, which we last saw change 18h ago.
Who they are
Clop is a ransomware which uses the .clop extension after having encrypted the victim's files. Another unique characteristic belonging with Clop is in the string: "Dont Worry C|0P" included into the ransom notes. It is a variant of CryptoMix ransomware, but it additionally attempts to disable Windows Defender and to remove the Microsoft Security Essentials in order to avoid user space detection.
Current status
Clop's leak site is answering our checks. That does not mean the group is actively posting — plenty of sites stay up for months with nothing new on them — but the infrastructure is live.
The last change we recorded on it was 18h ago (4 Sep 2026 19:06 UTC).
Which organisations this group has named, and when, is part of the SINON platform rather than this page. Create an account to search it, or to be told automatically if a name you care about turns up.
Sectors targeted
This group does not state an industry on its site, so we have nothing reliable to report. Most crews are opportunistic rather than sector-specific in any case — they hit what they can reach.
Watching for your name
If Clop posts your company, a supplier or a subsidiary, you want to hear it from us rather than from a journalist. SINON checks these sites continuously and alerts on the names you give it.
