This rule is designed to detect suspicious printer driver installations in Windows environments, specifically flagging instances where the Manufacturer value of the printer driver is empty. Empty Manufacturer values are often indicative of potentially malicious or unauthorized printer drivers that could be leveraged for privilege escalation attacks. The detection focuses on registry keys associated with printer drivers, particularly those under the 'Control\Print\Environments\Windows x64\Drivers' path. The rule includes specific filters to exclude benign entries related to popular printer drivers like CutePDF, VNC printers, and PDF24, ensuring that alerts are raised only for genuinely suspicious cases. Given its high severity level, organizations should closely monitor detections generated by this rule to preemptively address potential threats.
