The US Department of Health and Human Services (HHS) is warning healthcare organizations of the threat posed by ongoing Royal ransomware attacks.
Initially spotted in September 2022, the ransomware family is employed by a financially-motivated threat actor that also uses known tools for persistence, credential exfiltration, and lateral movement.
“Royal is a human-operated ransomware that was first observed in 2022 and has increased in appearance. It has demanded ransoms up to millions of dollars. Since its appearance, HC3 is aware of attacks against the Healthcare and Public Healthcare (HPH) sector,” the HHS warns.
Unlike other ransomware families out there, which employ the ransomware-as-a-service (RaaS) business model, Royal is operated by a private group, which likely consists of experienced actors from other groups, based on the use of elements from previous ransomware operations, the HHS says.
The group has been observed making ransom demands ranging from $250,000 to $2 million, but also stealing victim data to engage in double-extortion tactics, threatening to release the data publicly unless the ransom is paid.
The operation initially started with BlackCat’s encryptor, but then switched to Zeon (dropping a ransomware note like Conti’s), and in September changed their ransom note to Royal.
Roughly two weeks ago, Microsoft warned of infection chains leading to Royal ransomware that abuse Google ads for malvertising, bypass email protections by using contact forms, and use malicious installers on legitimate-looking websites and repositories.
“Royal is a newer ransomware, and less is known about the malware and operators than others. Additionally, on previous Royal compromises that have impacted the HPH sector, they have primarily appeared to be focused on organizations in the United States. In each of these events, the threat actor has claimed to have published 100% of the data that was allegedly extracted from the victim,” HHS notes.
