SysCook64 - Cooking thread contexts for fun and profit

What is this?

This is a PoC technique for indirect syscall execution, by suspending, altering and resuming a thread.
The target thread's context is modified in order to land on a syscall instruction in NTDLL (we're doing NtAllocateVirtualMemory), with registers and stack prepared for syscall execution.
There's no need for syscall stubs, since all the arguments are written directly to the target's thread context, while it's suspended.
