Microsoft’s Remote Desktop Protocol (RDP) is used for remotely connecting to Windows systems. In an RDP attack, criminals look for unsecured RDP services to exploit and access enterprise networks. It’s frighteningly easy to do so because many organizations fail to secure RDP services against improper access.

Over the past year, RDP has become the top attack vector for ransomware. Threat actors have repeatedly exploited internet-exposed RDP services to install ransomware on systems and networks belonging to numerous major organizations. In July, the SamSam group infected some 7,000 Windows PCs and 1,900 servers at LabCorp with ransomware via a brute force attack on an RDP server. In another incident this year, Hancock Health was forced to pay over $50,000 in ransom to regain access to critical data that criminals had encrypted after breaking into its network via a hospital server running RDP services.
