Remote Desktop Protocol (RDP) is the most dominant cyber security attack vector, and the most common ways of using RDP to gain access to a computer are the following:

Brute-force attack: the attackers attempt to sign in to an account by using trial-and-error methods. These can include repeatedly trying to log in with commonly used or stolen credentials, leading to many failed sign-ins occurring over very short time frequencies, typically minutes or even seconds.

Unpatched OS: the operating system is vulnerable to known Remote Desktop exploits. An example is BlueKeep, which allows the attacker to run malicious code in the kernel memory of the server, taking control of the entire system.
