Disclosure context

About lamashtu

Based on the limited available information, Lamashtu is an emerging ransomware group that was first observed in April 2026, appearing to be financially motivated based on their operational patterns. The group's origin and potential affiliations remain unclear due to their recent emergence and limited public documentation by major threat intelligence organizations. Lamashtu's attack methodology and specific technical capabilities have not been extensively documented by established security researchers, though their targeting patterns suggest they employ standard ransomware deployment techniques across multiple industry verticals. The group has conducted at least 8 confirmed attacks, demonstrating a geographically diverse targeting approach with victims identified in France, Italy, the United States, Singapore, and Malaysia, while focusing primarily on business services, manufacturing, transportation and logistics, hospitality and tourism, and energy sectors. Given the group's recent first observation in April 2026 and limited public threat intelligence reporting from established sources like CISA, FBI, or major security firms, Lamashtu appears to represent a newly active threat actor whose current operational status and long-term capabilities require further monitoring and analysis. The group has been linked to 34 public disclosures across our corpus. First observed on a leak site on April 13, 2026; most recent post June 17, 2026. The operation is currently active.

If your organisation is affected

A listing by lamashtu means Beaver Engineering 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 lamashtu'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.
