Executive Summary

ZeroFox Intelligence has observed an uptick in activity from the Royal Ransomware group (Royal), especially in the past two months. Royal gains access to victim networks by conducting targeted callback phishing attacks with the goal of convincing a victim to install remote access software, which is used to gain access to a corporate network. The group deploys Cobalt Strike for persistence, credential harvesting, lateral movement through a Windows domain, data stealing, and device encryption. Recently, the U.S. Department of Health and Human Services issued an advisory warning healthcare organizations in particular to be wary of Royal ransomware based on historic ransomware targeting of the healthcare industry.
