Disclosure context

About Rhysida

Rhysida is a ransomware group that emerged in June 2023, operating with primarily financial motivations through targeted attacks against critical infrastructure and public sector organizations. The group's origin and potential state affiliations remain unclear, though they operate independently rather than as a traditional Ransomware-as-a-Service model, with limited public documentation regarding connections to other cybercriminal organizations. Rhysida employs double extortion tactics, typically gaining initial access through compromised VPN credentials and exploiting vulnerable public-facing applications before deploying their ransomware payload and exfiltrating sensitive data prior to encryption. The group has demonstrated a particular focus on healthcare and educational institutions, with notable attacks documented by CISA and FBI advisories highlighting their targeting of hospitals and school districts across multiple countries, resulting in significant operational disruptions to critical services. As of late 2024, Rhysida remains an active threat with continued operations targeting organizations primarily in the United States, Canada, and other Western nations, maintaining their focus on high-value sectors where operational disruption can maximize ransom payment likelihood. The group has been linked to 324 public disclosures across our corpus. First observed on a leak site on June 5, 2023; most recent post September 13, 2026. The operation is currently active.

If your organisation is affected

A listing by Rhysida means Unknown US County Agency appeared on a ransomware extortion site and is being pressured to pay before any publication. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on Rhysida's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
