Disclosure context

About Royal

Royal is a financially motivated ransomware group that emerged in November 2022, quickly establishing itself as a significant threat with over 200 documented victims across multiple sectors. The group is believed to operate independently rather than as a ransomware-as-a-service model, though their exact country of origin remains unclear based on publicly available intelligence. Royal primarily gains initial access through phishing campaigns and exploitation of remote desktop protocols, subsequently deploying custom ransomware that encrypts victim files while exfiltrating sensitive data for double extortion tactics. The group has demonstrated a preference for targeting critical infrastructure and public services, with notable attacks against educational institutions, healthcare facilities, and government entities primarily in the United States, though they have also significantly impacted organizations across Germany, the United Kingdom, Canada, and France. Their encryption methodology involves custom-built malware that systematically encrypts files while maintaining persistence on compromised networks. As of recent reporting from federal agencies including CISA and FBI advisories, Royal remains an active threat with ongoing campaigns targeting organizations across their preferred sectors, particularly focusing on entities with limited cybersecurity resources that may be more likely to pay ransom demands. The group has been linked to 211 public disclosures across our corpus. First observed on a leak site on November 4, 2022; most recent post July 19, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Royal means Tucson Unified School District appeared on a ransomware extortion site and data attributed to it has been published. 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 Royal'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.
