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.
