Incident analysis

crownlaboratories.com was listed by Abyss ransomware, a group with 62 victims recorded in this database. The listing appeared on the group's leak site on April 2, 2025.

crownlaboratories.com is based in United States and operates in the Healthcare sector. United States ranks #1 worldwide for ransomware disclosures, with 10,149 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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