Miasm – reverse engineering framework for binary analysis

Miasm is a reverse engineering framework for analysing, modifying and generating binary programs. Rather than concentrating on a single stage of reverse engineering, it provides components spanning executable parsing, assembly, disassembly, intermediate representations, emulation and symbolic execution.

Its architecture makes Miasm particularly suited to researchers and developers building specialised analysis workflows. Instructions from different processor architectures can be represented using a common intermediate language, allowing further transformations and analyses to operate independently of the original instruction set.

This is free and open source software.

Key Features

• Open, modify and generate PE and ELF executables.
• Handle 32-bit and 64-bit binary formats.
• Support little-endian and big-endian targets where applicable.
• Assemble and disassemble x86, ARM, MIPS, SH4 and MSP430 instructions.
• Provide a common Machine abstraction across supported architectures.
• Represent assembly semantics using an intermediate language.
• Construct intermediate-representation control-flow graphs.
• Inspect read and write effects of intermediate expressions.
• Provide JIT-based emulation for dynamic code analysis.
• Support workflows involving unpacked or dynamically transformed code.
• Simplify expressions for automated de-obfuscation.
• Perform symbolic execution over intermediate representations.
• Inspect and modify registers and virtual memory during emulation.
• Add breakpoints and custom callbacks to emulated execution.
• Work with executable files as well as raw shellcode.
• Integrate into custom reverse-engineering scripts and applications.
