Ropper
Command-line tool and Python library for finding ROP and JOP gadgets in ELF, PE, and Mach-O binaries during exploit research.
Technical Architecture & Overview
Ropper is a CLI tool and Python library for finding Return-Oriented Programming (ROP) and Jump-Oriented Programming (JOP) gadgets in binary files. It supports ELF, PE, Mach-O, and Raw formats across x86, x86_64, ARM, ARM64, MIPS, MIPS64, PowerPC, PowerPC64, and SPARC64 architectures.
Targeted Technical Use Cases
Finding ROP and JOP gadgets for exploit development and assessing binary gadget density.
Evaluation & Trade-offs
Core Strengths
- +Supports multiple architectures including x86, x86_64, ARM, ARM64, MIPS, MIPS64, PowerPC, PowerPC64, and SPARC64.
- +Filter gadgets by register usage and instruction constraints with semantic search.
- +Embeds directly into Python scripts and binary analysis pipelines.
Trade-Offs & Limitations
- -Analyzing large shared libraries with complex gadgets requires noticeable processing time.
- -Specialized in gadget discovery rather than high-level decompilation.
Defensive Security Application
Evaluating gadget availability to assess the practical effectiveness of Control Flow Integrity and ASLR mitigations.
