Disclosure context

About exitium

Exitium is an emerging ransomware group that was first observed in March 2026, operating with apparent financial motivations based on their limited but documented attack patterns. Given the recent emergence and limited public documentation, specific details about the group's country of origin, organizational structure, or potential affiliations remain unclear to security researchers and law enforcement agencies. The group's attack methodology and technical capabilities have not been extensively documented due to their recent appearance and small victim count, though they appear to target specific sectors rather than conducting widespread campaigns. Exitium has been observed targeting organizations in the United States and Brazil, with a particular focus on the agriculture and food production sector as well as public sector entities, suggesting possible strategic targeting of critical infrastructure. The group remains active as of their recent emergence, though their limited victim count of two documented cases indicates they are either highly selective in their targeting, newly operational, or operating at a smaller scale compared to established ransomware groups. The group has been linked to 11 public disclosures across our corpus. First observed on a leak site on March 17, 2026; most recent post August 11, 2026. The operation is currently active.

If your organisation is affected

A listing by exitium means Mar Borges Agroindustria appeared on a ransomware extortion site and is being pressured to pay before any publication. 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, CERT.br (Brazil), as required for your jurisdiction.
Monitor for the data appearing on exitium'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.
