Blacktor is a relatively obscure ransomware group that emerged in December 2021 with apparent financial motivations, having targeted a limited number of victims since its inception. The group's origin and potential state affiliations remain unclear due to limited public reporting from major cybersecurity firms and government agencies, though their operational structure appears to be that of a small independent operation rather than a large-scale Ransomware-as-a-Service model. Technical details regarding Blacktor's attack methodology, including their preferred initial access vectors, encryption techniques, and whether they employ double or triple extortion tactics, have not been extensively documented in public threat intelligence reports from established sources such as CISA, FBI, or major security research organizations. With only four known victims documented since their emergence, Blacktor has not achieved the notoriety of major ransomware families and lacks publicly reported high-profile campaigns or significant law enforcement actions. The group's current operational status remains uncertain due to the limited visibility into their activities and the absence of recent public reporting on their campaigns. The group has been linked to 4 public disclosures across our corpus. First observed on a leak site on December 30, 2021. The operation is currently inactive.
If your organisation is affected
A listing by Blacktor means ticketclub-it 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.
- Monitor for the data appearing on Blacktor'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.
