Kernel imports (1)

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

API	Risk	Why it matters
KeBugCheckEx	medium	Moderate risk - system modification capability

IOCTL dispatch codes (2)

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
0x003403B4	medium	METHOD_BUFFERED	FILE_DEVICE_DISK Function #237

PE sections

Section layout and Shannon entropy. High entropy in a code section is a packing or encryption indicator.

Exploit mitigations

Control Flow Guard	Enabled
ASLR	Enabled
DEP	Enabled
Integrity check	Not enforced
Mitigation score	80 / 100

CFG Enabled - Control Flow Guard is active - indirect calls are validated against a bitmap of valid targets at runtime.
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.
Unsigned - The driver is not digitally signed. It requires test signing mode or a bootloader exploit to load on 64-bit Windows.

MITRE ATT&CK techniques (3)

Techniques this driver could enable if loaded by an adversary.

ID	Technique	Tactic
T1543.003	Windows Service	Persistence
