Incident analysis

UAB Biotecha was listed by Majinahanashi ransomware, a group with 42 victims recorded in this database. The listing appeared on the group's leak site on October 10, 2026.

UAB Biotecha is based in Lithuania and operates in the Healthcare sector. Lithuania ranks #88 worldwide for ransomware disclosures, with 9 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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