Incident analysis

Firmengruppe Hoffmann was listed by Spacebears ransomware, a group with 166 victims recorded in this database. The listing appeared on the group's leak site on December 30, 2025.

Firmengruppe Hoffmann is based in Germany and operates in the Construction sector. Germany ranks #2 worldwide for ransomware disclosures, with 1,003 victims in this database.

Sector context. Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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