PolyHook - x86/x64 Hooking Library

Provides abstract C++ 11 interface for various hooking methods

#Hooking Methods*:

1. Detour

• Description: Modifies opcode to jmp to hook and allocates a trampoline for jmp back
• Length Disassembler Support (Capstone)
• Supports Code Relocation, including EIP/RIP relative instructions

2. Virtual Function Detour :

• Description: Detours the function pointed to by the Vtable

3. Virtual Function Pointer Swap

• Description: Swaps the pointer in the Vtable to your hook

4. Virtual Table Pointer Swap

• Description: Swaps the Vtable pointer after copying pointers in source Vtable, then swaps virtual function pointer in the new copy

5. Import Address Table

• Description: Swaps pointer in the input address table to the hook

6. VEH

• Description: Intercepts an exception generated on purpose, sets instruction pointer to handler, then resets exception generating mechanism

• Methods to generate exception: INT3 Breakpoints, Guard Page violations.

• Note: it is important to call the GetProtectionObject function INSIDE of your callback as per my example for all VEH hooks

• Other exception generation methods are in development

• All methods support x86 and x64

• Relies on modified capstone branch https://github.com/stevemk14ebr/capstone

• More Information can be found at the wiki to the right
