# HellsVectoredGate

HellsVectoredGate is a technique that combaines VEH (Vectored Exception Handler)and indirect syscalls allowing the operator to execute native system calls through exception without directly invoking the syscall instruction in a traceable way. You must make specific exceptino (this case uses ACCESS_VIOLATION) so that registered VEH handle it.

### Usage

Initializing NTDLL_CONFIG and NT_API structures. Finding SSN of the syscalls and random syscall instruction address:
