T1652 - Device Driver Discovery

Description from ATT&CK

Adversaries may attempt to enumerate local device drivers on a victim host. Information about device drivers may highlight various insights that shape follow-on behaviors, such as the function/purpose of the host, present security tools (i.e. Security Software Discovery) or other defenses (e.g., Virtualization/Sandbox Evasion), as well as potential exploitable vulnerabilities (e.g., Exploitation for Privilege Escalation).

Many OS utilities may provide information about local device drivers, such as driverquery.exe and the EnumDeviceDrivers() API function on Windows.(Citation: Microsoft Driverquery)(Citation: Microsoft EnumDeviceDrivers) Information about device drivers (as well as associated services, i.e., System Service Discovery) may also be available in the Registry.(Citation: Microsoft Registry Drivers)

On Linux/macOS, device drivers (in the form of kernel modules) may be visible within /dev or using utilities such as lsmod and modinfo.(Citation: Linux Kernel Programming)(Citation: lsmod man)(Citation: modinfo man)
