Doommageddon is a ransomware group first observed in July 2026 with an apparent primary motivation of financial gain, though limited public documentation exists given the group's recent emergence and relatively small operational footprint to date. Based on available data, the group has claimed or been attributed responsibility for approximately five known victims, with targeting concentrated in Turkey, Brazil, India, and Paraguay, suggesting a broad, opportunistic geographic scope rather than a regionally focused operational mandate. Targeted sectors include manufacturing, consumer services, financial services, and technology, a diverse vertical spread consistent with an opportunistic or nascent RaaS model still establishing its targeting criteria; no confirmed affiliation with established threat actor clusters or nation-state sponsors has been publicly documented by CISA, the FBI, Mandiant, or other reputable threat intelligence sources at this time. Specific initial access vectors, tooling, and encryption methodologies employed by Doommageddon have not been publicly detailed in available open-source or vendor reporting, and no confirmed double or triple extortion data leak site has been publicly attributed to the group by credible researchers. Given the group's first observation date of July 2026 and the very limited victim count, Doommageddon should be assessed as an emerging or low-maturity threat actor whose tactics, techniques, and procedures remain largely undocumented, and analysts should treat any further attribution or capability claims with appropriate caution pending additional corroborating intelligence. The group's current operational status cannot be definitively assessed beyond confirmation of initial activity in mid-2026. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on July 6, 2026; most recent post July 10, 2026. The operation is currently active.
If your organisation is affected
A listing by Doommageddon means Hospital Di Camp 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 Doommageddon'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.
