350 Victims of Royal Ransomware Asked to Pay $275 Million

The Royal ransomware gang has targeted more than 350 organizations worldwide, demanding ransoms that collectively exceed $275 million. This information comes from a joint advisory by the Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA), highlighting the extensive reach and sophisticated tactics of the cybercriminal group.

Since September 2022, Royal ransomware has been used to compromise organizations across the globe, with phishing emails being identified as one of the most successful methods of initial access. The FBI and CISA noted that the group conducts data exfiltration before encrypting the victim’s systems, and publishes the stolen data on a leak site if the ransom is not paid.

The Royal ransomware group is believed to mainly comprise former operatives of the Conti ransomware group, and has been particularly active in the past year. The group's attacks have included significant data breaches, such as the exfiltration of over 1.1 TB of data from the City of Dallas, which compromised information belonging to more than 30,000 individuals.

The FBI and CISA have also warned that there are indications Royal may be preparing to rebrand or split into two threat groups, with apparent links to another ransomware gang, BlackSuit.

The cybersecurity advisory was updated in November 2023, offering refreshed indicators of compromise (IOCs) and up-to-date tactics, techniques, and procedures (TTPs). This update includes IOCs generated by FBI investigations earlier this year, showing a crossover between Royal and the Blacksuit ransomware group. The advisory states, "Royal and Blacksuit threat actors have been observed using legitimate software and open-source tools during ransomware operations."

As reported before, the Royal ransomware group's modus operandi involves encrypting their targets' enterprise systems and demanding substantial ransoms, ranging from approximately $1 million to $11 million in Bitcoin. In observed incidents, Royal actors do not include ransom amounts and payment instructions as part of the initial ransom note. Instead, the note requires victims to interact directly with the threat actor via a.onion URL.

The situation highlights the significant threat posed by ransomware gangs to organizations globally. The FBI and CISA have issued detailed advisories to help organizations detect and prevent ransomware attacks, emphasizing the importance of robust cybersecurity measures and international cooperation in combating cybercrime.
