Who they are

Groove was a short-lived ransomware group and cybercrime gang that emerged in August 2021 and became notable for its aggressive, publicity-driven tactics. Unlike traditional Ransomware-as-a-Service (RaaS) groups, Groove functioned more as a loose criminal collective, encouraging other threat actors to join forces in attacking U.S. entities, particularly in the government and financial sectors. The group ran a Tor-based leak site where it published stolen data, but its operators claimed to focus more on building an “underground alliance” than on ransomware deployment itself. Analysts noted overlaps between Groove and actors behind Babuk and BlackMatter, as well as forum personas known for data theft operations. By early 2022, Groove’s activity had largely ceased, with some experts suggesting the group was either a short-term recruitment campaign or a misinformation effort.

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

Groove's leak site is not answering. Sites go dark for infrastructure trouble, a deliberate quiet period, or a takedown, and a good number return weeks later under the same name, so the entry stays on the list either way.

The last change we recorded on it was 5y ago (30 Oct 2021 10:50 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.

Watching for your name

If Groove 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.
