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.
