angrop
Python extension for angr that automatically generates ROP chains using symbolic execution and constraint solving methods.
Technical Architecture & Overview
angrop is an open-source ROP chain builder that uses angr's symbolic execution engine to automatically generate ROP chains. It supports x86, x64, ARM, AArch64, MIPS, and 64-bit RISC-V architectures, and can generate complex chains that satisfy specific register and memory constraints.
Targeted Technical Use Cases
Automated ROP chain generation for exploit development and binary analysis research.
Evaluation & Trade-offs
Core Strengths
- +Uses symbolic execution to automatically find and chain gadgets, reducing manual effort.
- +Supports x86, x64, ARM, AArch64, MIPS, and 64-bit RISC-V architectures.
- +Integrates with the angr framework for combined symbolic execution and ROP analysis.
Trade-Offs & Limitations
- -Fast mode, selected by default from the binary size, skips gadgets with conditional branches, which can limit the gadgets available.
- -Requires angr installation and familiarity with symbolic execution concepts.
Defensive Security Application
Automated evaluation of ROP chain feasibility in binaries.
