Use a windows server with inbound RDP? Time to think again (ASAP) about security!


Computers with Windows Remote Desktop Protocol (RDP) exposed to the internet are an attractive target for adversaries because they present a simple and effective way to gain access to a network. Brute forcing RDP, a secure network communications protocol that provides remote access over port 3389, does not require a high level of expertise or the use of exploits; attackers can utilize many off-the-shelf tools to scan the internet for potential victims and leverage similar such tools for conducting the brute force attack.

Attackers target RDP servers that use weak passwords and are without multi-factor authentication, virtual private networks (VPNs), and other security protections. Through RDP brute force, threat actor groups can gain access to target machines and conduct many follow-on activities like ransomware and coin mining operations.
