Internet UDP port 135 is primarily used by Microsoft Windows for its Distributed Component Object Model services (DCOM). This system allows for communication between software components distributed across networked computers, enabling them to interact and share information. It is also used by the Microsoft End Point Mapper, which helps in managing RPC connections. However, it's worth noting that this port is often targeted by malicious software due to its widespread use in Windows environments.
UDP port 135 is known for its association with Microsoft's Distributed Component Object Model (DCOM) services. In the past, hackers have exploited this port to execute Distributed Denial of Service (DDoS) attacks, causing systems to become unresponsive. Additionally, it has been used to spread malware or worms like the Blaster Worm, which exploited a DCOM RPC vulnerability. Hackers have also used this port for port scanning and system enumeration, gathering information about the target system to plan further attacks. Furthermore, unauthorized access and remote code execution have been possible when this port is left open and unsecured.
