Disclosure context

About INC Ransom

INC Ransom is a financially motivated ransomware group that emerged in September 2021 and has since compromised 832 known victims across multiple sectors. The group's origin and specific affiliations remain undocumented in public threat intelligence reports, though their operational patterns suggest they likely operate as an independent entity rather than a formal Ransomware-as-a-Service model. While detailed attack methodologies for INC Ransom have not been extensively documented by major security firms, their victim distribution indicates they employ broad-spectrum targeting approaches that have successfully penetrated healthcare, technology, business services, and manufacturing organizations. The group demonstrates a preference for targeting English-speaking countries, with the United States, Canada, and United Kingdom representing their primary victim demographics, alongside significant activity in Germany and Australia. Notable campaigns or high-profile attacks by INC Ransom have not been prominently featured in major threat intelligence publications from CISA, FBI, or leading security researchers, suggesting they may operate with a lower public profile despite their substantial victim count. INC Ransom remains active as of current intelligence assessments, with no documented law enforcement disruptions or confirmed rebranding efforts. The group has been linked to 853 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post June 6, 2026. The operation is currently active.

If your organisation is affected

A listing by INC Ransom means PK PINHÃO & KOIFFMAN ATTORNEYS AT LAW 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 INC Ransom's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
