What it detects

This rule detects execution of srvhost.exe, a filename Head Mare uses to masquerade its Sliver implant and helper binaries as the legitimate Windows svchost service host. Because no genuine Windows component is named srvhost.exe, its execution is a reliable indicator of the group's tooling.
