⛓️ ROP Chain Calculator Desktop WIP

What is it?

The WinDbg-integrated companion to the browser ROP Chain Calculator. A set of Python scripts that run inside WinDbg via PyKD, automating the grunt work of building multi-stage ROP chains against live targets.

What's in the Toolset

• IAT Scanner — scans all loaded modules for IAT entries pointing to VirtualAlloc and WriteProcessMemory. Gives you the exact IAT slot address to dereference in your ROP chain for reliable dynamic resolution.
• Gadget Sequence Parser — parses binary files for gadget sequences in binary format, supporting automated gadget data generation
• Stage 2 Generator — assists in building multi-stage payloads where stage 1 ROP bootstraps stage 2 shellcode via VirtualAlloc/WriteProcessMemory
• Single ROP Tester — isolated testing harness for verifying individual gadget chains before assembling the full chain

Requirements

• WinDbg with PyKD installed (.load pykd.pyd)
• Target process loaded in WinDbg
