The FBI has warned that over 30 US-based companies had been hit by the Ranzy Locker ransomware by July this year, in a flash alert to other organisations who may be at risk.
According to the alert, issued with the Cybersecurity and Infrastructure Security Agency (CISA), most of the victims were compromised after brute force credential attacks targeting Remote Desktop Protocol (RDP) to gain access to targets’ networks.
Recent victims, according to the FBI, have reported that the malicious hackers exploited known vulnerabilities in Microsoft Exchange Server and phishing attacks as a way of compromising systems.
