Disclosure context

About MS13-089

MS13-089 is a ransomware group first observed in May 2026 with an apparent financial motivation, though its limited documented activity makes comprehensive attribution difficult at this time. Based on available data, the group has claimed or been linked to a single known victim, with targeting focused on the United States and specifically the Healthcare and Social Services sector, a pattern consistent with threat actors who deliberately select high-pressure targets likely to pay ransoms quickly to restore critical operations. No public reporting from CISA, the FBI, Mandiant, or other established threat intelligence sources has yet documented the group's specific initial access vectors, tooling, encryption methods, or affiliation with known ransomware ecosystems, and it remains unclear whether MS13-089 operates as a Ransomware-as-a-Service platform or as an independent closed group. Given its extremely recent emergence and minimal victim footprint at the time of this writing, MS13-089 should be considered an emerging and under-documented threat, and the Healthcare sector in particular should monitor for indicators of compromise as the group's tactics, techniques, and procedures become more clearly defined through ongoing incident investigations and threat intelligence collection. Current status remains active based on first observation date, though the full scope of its operations has yet to be established in open-source reporting. The group has been linked to 9 public disclosures across our corpus. First observed on a leak site on May 14, 2026; most recent post August 23, 2026. The operation is currently active.

If your organisation is affected

A listing by MS13-089 means Unnamed Maritime Company 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.
  • Monitor for the data appearing on MS13-089'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.
