The WannaCry ransomware halted thousands of computers around the world in the spring of TCP port was mostly used to infect the virus. The user only requires access to it in very rare circumstances, but the computer is always listening to it.

Today, here we learn what is the need for port and why we should close it, if not required. TCP port is used for this.

The SMB Server Message Block can also carry transaction protocols for inter-process communication that is authenticated. SMB is used by clients to access data on servers. This enables file sharing, centralized data management, and reduced storage requirements for mobile devices.

It is also used by servers in the Software-defined Data Center for tasks like clustering and replication. Depending on the application, TCP Port may interact via a predefined protocol. A protocol is a collection of codified rules that describe how data is transmitted across a network. Consider it the language used by computers to let them converse more efficiently. TCP guarantees data delivery as well as packet delivery on port in the same sequence in which they were transmitted.

WannaCry used legacy versions of Windows machines running an out-of-date version of the SMB protocol. It is a network worm with a transport mechanism that allows it to spread autonomously.
