A security engineer has been informed by the firewall team that a specific Windows workstation...

Netstat is a command-line tool that can be used to find the malicious process that is using a specific port on a Windows workstation. Netstat displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols). To find the process that is using a specific port, such as TCP 40322, the security engineer can use the following command:

netstat -ano | findstr :40322

This command will filter the netstat output by the port number and show the process identifier (PID) of the process that is using that port. The security engineer can then use the task manager or another tool to identify and terminate the malicious process by its PID. Verified References:
