Disclosure context

About Trigona

Trigona is a relatively new ransomware group that emerged in April 2023, operating with primarily financial motivations and targeting organizations across multiple sectors globally. The group's origin and specific affiliations remain unclear based on publicly available intelligence, though their targeting patterns suggest they operate as an independent entity rather than a established Ransomware-as-a-Service operation. Trigona employs double extortion tactics, combining data encryption with data exfiltration and threats to publish stolen information on leak sites, though specific details about their initial access vectors and encryption methods have not been extensively documented by major security researchers. The group has claimed 49 victims as of current reporting, with their attacks concentrated in the United States, Australia, Mexico, France, and Indonesia, primarily targeting business services, manufacturing, healthcare, technology, and finance sectors. Given the group's recent emergence in 2023, there are no widely reported major campaigns or significant law enforcement actions documented by CISA, FBI, or established threat intelligence firms. Trigona appears to remain active as of current intelligence assessments, though the limited public documentation reflects their relatively recent entry into the ransomware landscape. The group has been linked to 49 public disclosures across our corpus. First observed on a leak site on April 17, 2023; most recent post March 30, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Trigona means Treadwell, Tamplin & Company, Certified Public Accountants, Madison, GA 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 Trigona's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
