Cyberleek ransomware group

Who they are

No published writeup exists for Cyberleek that we would stand behind, which is common for newer and short-lived crews. What we can say comes from the site itself: it is responding to our checks, and it states no industry for what it posts.

Descriptions are compiled from public reporting and vendor research. They describe how a group has historically operated and can lag its current behaviour; the status and timings above are our own.

Current status

Cyberleek'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 19h ago (4 Sep 2026 19:17 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

Industries this group has been observed going after, most common first.

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.

Leak site capture

Cyberleek's extortion site as we last captured it, served through our own origin — opening the real thing would put you on their infrastructure.
