About the Trinity group

Trinity ransomware was first discovered in May 2024, believed to be a rebrand of the Venus/2023Lock variants, using ChaCha20 encryption and double-extortion via a Tor leak site; the US HHS flagged it as a specific threat to the healthcare sector after confirmed attacks on healthcare organizations. Trinity has listed 18 victims since June 2024.

Sector context. Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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