The FBI yesterday alerted U.S. organizations to ransomware attacks by a group using phishing emails to access victim networks and download Cobalt Strike threat emulation software. The alert includes indicators of compromise associated with attacks by the so-called OnePercent Group and recommended mitigation actions for affected organizations. 

John Riggi, AHA senior advisor for cybersecurity and risk, said, “The relatively low profile OnePrecent ransomware group is using common tactics such as phishing emails for initial compromise, then common technical tools such as Cobalt Strike and Powershell to spread the ransomware throughout the victim network. As we have seen several high-impact ransomware attacks targeting hospitals and health systems since Aug. 2, I recommend that any and all ransomware alerts issued by the government be given special attention. I and the AHA are closely coordinating with FBI, the Cybersecurity & Infrastructure Security Agency and HHS to exchange information relevant to ransomware attacks for the benefit of the field.”
