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.

Incident analysis

Biotehnos was listed by Lamashtu ransomware, a group with 63 victims recorded in this database. The listing appeared on the group's leak site on April 16, 2026.

Biotehnos is based in Romania and operates in the Healthcare sector. Romania ranks #44 worldwide for ransomware disclosures, with 62 victims in this database.

Sector context. Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .

How can organisations protect against Lamashtu attacks?

To defend against Lamashtu and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
