Disclosure context

About Incransom

Incransom is a ransomware group that emerged in August 2023, operating with primarily financial motivations as evidenced by their targeting of high-value sectors across multiple developed nations. The group's origin and specific affiliations remain undocumented by major threat intelligence organizations, though their operational patterns suggest they likely operate independently rather than as a ransomware-as-a-service model. With 734 documented victims, Incransom has demonstrated a preference for targeting organizations in the United States, Canada, United Kingdom, Germany, and Australia, with particular focus on healthcare, technology, business services, and manufacturing sectors, though their attack methodology and specific technical capabilities have not been extensively documented by established security researchers or government agencies. The group's notable campaigns and specific high-profile victims have not been publicly detailed by CISA, FBI, Mandiant, or other reputable threat intelligence sources, suggesting either operational security effectiveness or limited visibility into their most significant operations. Based on available intelligence, Incransom appears to remain active as of recent reporting periods, though comprehensive analysis of their current operational status requires additional documentation from established threat intelligence sources. The group has been linked to 1,814 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post October 1, 2026. The operation is currently active.

If your organisation is affected

A listing by Incransom means Rimrock Foundation 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 Incransom'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.
