About the Abyss group

Abyss (also known as Abyss Locker) is a ransomware operation first identified in March 2023, derived from the Babuk source code, that targets Windows and Linux/VMware ESXi systems using double-extortion tactics across healthcare, manufacturing, finance, and technology sectors — predominantly in North America.

Incident Analysis

hptc.org was targeted by Abyss ransomware, one of the most active ransomware groups in our database with 62 confirmed victims globally. The attack was disclosed on July 26, 2025, when hptc.org appeared on the group's dark web leak site.

hptc.org is based in United States , operating in the Healthcare sector. United States ranks #1 globally for ransomware attacks, with 9,425 victims in our 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 employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
