Silver Fox RMM Tool IPv4 Filename Abuse
Detects the execution of an RMM tool where the filename is prepended with an IPv4 address (e.g., '45.119.55.66ClientSetup.exe'). This technique is actively used by the Silver Fox (Void Arachne) intrusion set to pass Command and Control (C2) IP addresses directly to the legitimate SyncFutureTec RMM tool, evading signature-based detection while maintaining the binary's valid digital signature.
