Kernel-mode APIs resolved from the Import Address Table of plnu3v.sys, ranked by exploitation relevance.
| API | Risk | Why it matters |
|---|---|---|
| MmGetSystemRoutineAddress | high | Potentially dangerous - could be used for privilege escalation or security bypass |
| KeBugCheckEx | medium | Moderate risk - system modification capability |
| RtlInitUnicodeString | low | Standard kernel API - generally benign |
| DbgPrint | low | Standard kernel API - generally benign |
| ExAllocatePoolWithTag | low | Standard kernel API - generally benign |
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.
