Disclosure context

About ms13089

ms13089 is an emerging ransomware group first observed in December 2025, appearing to be financially motivated based on their limited operational profile. The group's origin and affiliations remain unknown due to their recent emergence and limited public documentation, with no confirmed information available regarding their operational model or geographic base. Given the lack of detailed technical analysis from major security firms, their specific attack methodologies, initial access vectors, and encryption techniques have not been publicly documented by reputable threat intelligence sources. The group has targeted three known victims across Germany, Luxembourg, and Italy, though no high-profile campaigns or notable incidents have been reported by CISA, FBI, or established security researchers. As of early 2025, ms13089 appears to remain active but maintains a low profile with minimal public intelligence available about their operations. The group has been linked to 4 public disclosures across our corpus. First observed on a leak site on December 18, 2025; most recent post May 5, 2026. The operation is currently active.

If your organisation is affected

A listing by ms13089 means brittanyresidential.com 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 ms13089'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.
