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.
