Goal

Detects when a suspicious remote named pipe is observed, which could indicate lateral movement or remote execution attempts by malicious actors.

Strategy

Monitoring of Windows event logs where @evt.id is 5145 and grouping by @Event.System.Computer, where A network share object was checked to see whether client can be granted desired access. The value that was observed was unusual, which made it suspicious.

Triage & Response

Verify if the exection of the suspicious pipe on {{@@Event.System.Computer}} is expected. If the execution was not intended isolate the system.
