What it detects

This rule detects the Windows Contacts import utility wabmig.exe initiating outbound network connections. The Turian backdoor injects into wabmig.exe, an application with no legitimate need for network communication, to mask its command-and-control traffic. Outbound connections from this process strongly indicate process injection and active C2.
