What it detects
This rule flags process creation events where VMware Xfer utility (VMwareXferlogs.exe) runs from a directory outside the expected default VMware installation path. Attackers may use legitimate VMware utilities placed or launched from non-standard locations to load malicious DLLs or persist while blending in with trusted tooling. It relies on Windows process creation telemetry, matching the executable filename suffix and excluding the typical installation directory prefix.
