About the Lamashtu group

Lamashtu is an extortion group that first appeared in April 2026, claiming attacks against organizations in France, Romania, and Thailand across energy, pharmaceutical, and film sectors; it has not yet been confirmed as operating actual file-encrypting ransomware rather than pure data-theft extortion. Lamashtu has listed 48 victims since April 2026.

Sector context. Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Lamashtu typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
