Incident analysis

Lambertinum Seniorenwohnanlage was listed by Wallstreet ransomware, a group with 50 victims recorded in this database. The listing appeared on the group's leak site on October 13, 2026.

Lambertinum Seniorenwohnanlage is based in Germany and operates in the Healthcare sector. Germany ranks #2 worldwide for ransomware disclosures, with 987 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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