Disclosure context

About Gammax

Gammax is a ransomware group first observed in July 2026 with an apparently financial motivation, though limited public documentation exists given its nascent operational history and very low victim count. With only two known victims on record, the group remains largely uncharacterized by major threat intelligence organizations such as CISA, FBI, Mandiant, or comparable research bodies, and no definitive attribution regarding country of origin, affiliation with established threat actors, or ransomware-as-a-service infrastructure has been publicly established at this time. Based on available victimology data, Gammax has demonstrated a targeting preference for organizations in Canada and Colombia, with activity concentrated in the Energy and Utilities and Retail and E-Commerce sectors, suggesting either opportunistic targeting of these verticals or a deliberate focus on industries where operational disruption may increase pressure to pay. No specific initial access vectors, encryption methodologies, or extortion tactics have been publicly attributed to this group by authoritative sources, and no notable high-profile campaigns, record ransom demands, or law enforcement actions have been publicly documented against them. Given its July 2026 emergence and minimal victim footprint, Gammax should be considered an emerging and closely monitored threat, though its current operational status, true capabilities, and trajectory remain insufficiently documented to support more definitive analytical conclusions. The group has been linked to 11 public disclosures across our corpus. First observed on a leak site on July 30, 2026; most recent post August 10, 2026. The operation is currently active.

If your organisation is affected

A listing by Gammax means Sari Office Building 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 Gammax'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.
