Incident analysis

Constellation HomeBuilder Systems was listed by Unsafe ransomware, a group with 19 victims recorded in this database. The listing appeared on the group's leak site on August 9, 2026.

Constellation HomeBuilder Systems is based in United States and operates in the Manufacturing sector. United States ranks #1 worldwide for ransomware disclosures, with 9,991 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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