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.

CNS is based in China. China ranks #28 worldwide for ransomware disclosures, with 127 victims in this database.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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