Kernel imports (4)

Kernel-mode APIs resolved from the Import Address Table of FWVirtualInputDevice.sys, ranked by exploitation relevance.

API	Risk	Why it matters
KeBugCheckEx	medium	Moderate risk - system modification capability
RtlInitUnicodeString	low	Standard kernel API - generally benign
IoDeleteSymbolicLink	low	Standard kernel API - generally benign
IoCreateSymbolicLink	low	Standard kernel API - generally benign

IOCTL dispatch codes (4)

Control codes reachable through the driver dispatch routine. Codes tied to published exploit code are flagged, since they are the primary Bring Your Own Vulnerable Driver (BYOVD) entry points.

Code	Severity	Transfer	Description
0x002200F0	medium	METHOD_BUFFERED	FILE_DEVICE_UNKNOWN Function #60
0x0034B305	medium	METHOD_IN_DIRECT	FILE_DEVICE_DISK Function #3265

Exploit mitigations

Control Flow Guard	Not enabled
ASLR	Enabled
DEP	Enabled
Integrity check	Not enforced
Mitigation score	55 / 100

No CFG - Control Flow Guard is not enabled. Indirect call targets are not validated, making the driver susceptible to control flow hijacking via corrupted function pointers or vtables.
ASLR Enabled - Address Space Layout Randomization is active - base address is randomized on each load.
DEP/NX Enabled - Data Execution Prevention is active - non-executable pages cannot be executed.
Expired Certificate - The driver is signed but the certificate has expired. Windows may still load it depending on revocation policy.

MITRE ATT&CK techniques (4)

Techniques this driver could enable if loaded by an adversary.
