Who they are

Karakurt is a financially motivated cybercrime group first publicly identified in June 2021, specializing in data extortion without file encryption. Instead of deploying ransomware to lock systems, Karakurt focuses on gaining access to victim networks, exfiltrating sensitive data, and threatening to leak it on its Tor-based site unless payment is made. The group has targeted victims across North America and Europe in industries including healthcare, manufacturing, education, and professional services. Intrusion methods include phishing, exploitation of vulnerabilities, and purchasing access from initial access brokers. Karakurt’s leak site lists stolen files in stages to pressure victims, sometimes publishing entire data sets if ransoms are not paid. The group is believed to have operational links to the Conti ransomware syndicate, based on shared infrastructure, overlapping victimology, and timing of activity.

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

Karakurt'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 3d ago (2 Sep 2026 05:29 UTC).

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 Karakurt 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.
