Internet TCP port 3389 is primarily used by Microsoft's Remote Desktop Protocol (RDP). This protocol allows for remote control of a computer system from another device over the internet. Examples of software that utilize this port include Microsoft's Remote Desktop Connection and Remote Desktop Services. Other third-party software, such as rdesktop, also use this port to provide similar remote desktop capabilities.
TCP port 3389 is commonly used for Microsoft's Remote Desktop Protocol (RDP). In the past, hackers have exploited this port to gain unauthorized access to systems. They typically do this by using brute force attacks to guess weak passwords and gain control of the RDP. Once they have access, they can install malicious software, steal data, or use the system as part of a botnet. For instance, the infamous GoldBrute botnet was known to specifically target this port. Therefore, it's crucial to secure systems using strong passwords and other security measures.
