Titan is a ransomware group first observed in May 2026, representing an emerging threat actor with limited publicly documented history at this time; their primary motivation appears to be financial based on observed targeting patterns. Given the recency of their emergence and the limited victim count of seven confirmed victims, comprehensive attribution and affiliation details remain unclear, and it is unknown at this time whether they operate as a Ransomware-as-a-Service model or as an independent closed group with no confirmed links to previously documented threat actors. Their targeting profile spans multiple geographies including the United States, Mexico, Singapore, France, and Tunisia, suggesting an opportunistic rather than regionally focused operational approach, with victimology concentrated in the Business Services and Manufacturing sectors; specific tools, initial access vectors, and encryption methodologies have not yet been publicly documented by CISA, the FBI, Mandiant, or other reputable security research organizations as of this profile's preparation. Notable campaigns are limited given the group's nascent operational timeline, with only seven known victims identified and no record ransoms, landmark incidents, or law enforcement actions publicly attributed to this group at this stage. Titan should be considered an emerging and developing threat requiring continued monitoring as their operational tempo, tooling, and affiliations become more clearly established through future incident reporting and threat intelligence collection. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on May 18, 2026; most recent post July 13, 2026. The operation is currently active.

If your organisation is affected
A listing by titan means Eureka Construction INC 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 titan'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.
