What it detects

This rule detects the XRed backdoor establishing persistence through a Run key value named Synaptics Pointing Device Driver that points into the ProgramData\Synaptics directory. The value name masquerades as a legitimate touchpad driver while the executable path is a non-standard ProgramData location dropped by trojanized InstantView installers. Attackers use this autorun entry to survive reboots and maintain backdoor access for keylogging and data theft.
