Detects the execution of the Windows finger.exe utility with a command-line argument containing an '@' symbol, which indicates a request to a remote host. This technique is often abused by adversaries for reconnaissance or to retrieve remote stagers or other payloads, as the finger protocol is rarely used in modern enterprise environments.
