Disclosure context

About Karakurt

Karakurt is a ransomware group that emerged in December 2022, operating primarily as a data extortion threat actor with financial motivations rather than traditional file encryption. The group's origin and affiliations remain largely undocumented by major cybersecurity agencies, though their operational patterns suggest they function as an independent entity rather than a confirmed ransomware-as-a-service operation. Karakurt employs data theft and extortion tactics, focusing on exfiltrating sensitive information from victim networks before demanding payment under threat of public disclosure, representing a pure extortion model that bypasses traditional encryption-based ransomware approaches. The group has targeted 74 known victims across multiple sectors, with particular focus on healthcare, education, manufacturing, energy, and professional services organizations, primarily affecting entities in the United States, United Kingdom, Germany, Singapore, and India. Based on available reporting from established cybersecurity agencies and researchers, Karakurt appears to remain active as of recent assessments, though comprehensive intelligence on their specific attack vectors, tools, and major campaigns remains limited in publicly documented sources from CISA, FBI, and major security research organizations. The group has been linked to 74 public disclosures across our corpus. First observed on a leak site on December 11, 2022; most recent post September 22, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Karakurt means Goodwill industries appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on Karakurt's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
