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 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 RISC-V architectures.
  • +Integrates with the angr framework for combined symbolic execution and ROP analysis.

Trade-Offs & Limitations

  • -Symbolic execution is computationally expensive and may not scale to very large binaries.
  • -Requires angr installation and familiarity with symbolic execution concepts.

Defensive Security Application

Automated evaluation of ROP chain feasibility to assess the practical effectiveness of control-flow integrity mitigations.
