The FBI and DHS issued a joint warning to consumers and businesses on the increasing use of the Remote Desktop Protocol (RDP) administration tool as an attack vector.
The notice said RDP attacks have been on the rise since 2016 ,with attackers using open RDP ports to take over machines or intercepting RDP sessions and injecting various types of malware into the system being remotely accessed. In other cases computers with RDP software on board have been victimized when attackers used brute-force techniques to gain usernames and passwords.
The two law enforcement agencies said CrySIS, CryptON and SamSam ransomware have all been spread through RDP attacks. CrySiS has mainly been used against U.S. businesses that have computers with open RDP ports. Here attackers use brute-force and dictionary attacks to gain unauthorized remote access and then CrySiS is dropped onto the device and a ransom is demanded.
