Rhysida is a ransomware and double-extortion group first publicly observed in May 2023, operating an affiliate-style model and publishing stolen data on a Tor leak site. It is known for high-profile attacks on public-sector and critical-service targets, including Prospect Medical Holdings, the British Library, and the Chilean Army (all 2023). Several researchers have suggested overlap with the Vice Society actor, citing shared tactics such as intermittent encryption, though this remains unconfirmed. Per this dashboard, the group's leak site posted 2 victims in the past 30 days, most recently on 2026-09-08, including publication of stolen Berlin state government login credentials after a reported €2 million extortion demand was refused (news reporting, 2026). No comprehensive public earnings estimate for the group has been identified.

Tactics & tooling
  • Initial access via phishing emails with malicious links or attachments (vendor reporting, 2023)
  • Use of legitimate remote monitoring/management and remote-access tools in intrusions
  • Double extortion: data exfiltration followed by publication on a Tor leak site
  • Public auctions of stolen victim data on cybercrime markets (reported 2023, e.g., Prospect Medical Holdings)
  • C-based ransomware encryptor using ChaCha20 for file encryption with RSA-4096-protected keys (analyst analyses, 2023)
  • Intermittent/partial encryption in some incidents, a technique also associated with the Vice Society actor
  • Recruitment of affiliates via cybercrime forums (reported 2023)
  • Targeting skewed toward healthcare, education, government, and cultural institutions, though activity is opportunistic
