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 30 public disclosures across our corpus. First observed on a leak site on April 13, 2026; most recent post May 19, 2026. The operation is currently active.
