Suspicious Command Execution with Ping and File Deletion

Detects suspicious command-line activity involving 'cmd.exe' executing 'ping' to the loopback address (127.0.0.1) combined with an ampersand ('&') and a file deletion command ('del', 'delete', or 'erase'). This pattern is often indicative of an attacker attempting to test network connectivity or bypass security controls while also performing cleanup or destructive actions.
