Disclosure context

About m3rx

Based on the limited publicly available information, m3rx is an emerging ransomware group first observed in April 2026 with a relatively small victim count of eight organizations, suggesting they are either a newly formed operation or a smaller-scale criminal enterprise focused on financial gain. The group's origin and affiliations remain unclear, with no documented evidence from major security vendors or law enforcement agencies regarding their geographical base, operational structure, or whether they operate as an independent cell or as part of a larger ransomware-as-a-service ecosystem. Their attack methodology and specific technical capabilities have not been extensively documented by established threat intelligence sources, though their targeting pattern indicates a preference for English-speaking nations including Great Britain, Australia, and the United States, as well as operations in Switzerland and Italy, with victims spanning consumer services, business services, technology, and healthcare sectors. No major campaigns, high-profile victims, or significant ransoms have been publicly reported by CISA, FBI, Mandiant, or other reputable security researchers, likely due to the group's recent emergence and limited scope of operations. Given their recent first observation date and small victim count, m3rx appears to be in early operational stages with their current activity status and long-term viability remaining uncertain. The group has been linked to 38 public disclosures across our corpus. First observed on a leak site on April 29, 2026; most recent post August 29, 2026. The operation is currently active.

If your organisation is affected

A listing by m3rx means lindner-group.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, CERT.at (Austria), as required for your jurisdiction.
  • Monitor for the data appearing on m3rx'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.
