Fission

Building trustworthy open-source systems for binary analysis and decompilation.
README.md
Fission — reverse engineering workspace

A Rust-native platform for binary analysis, reverse engineering, and program understanding

CI Latest Release License Rust

Fission

A multi-layered reverse engineering workspace built in Rust.

Analysis

  • Binary lifting via Ghidra SLEIGH → P-code
  • NIR/HIR structuring and pseudocode output
  • Static analysis: xrefs, strings, discovery
  • Function signature matching (FID)
  • PE, ELF, Mach-O — x86 / x86-64 primary

Execution & Verification

  • P-code emulator with OS HLE
  • Dynamic analysis and unpacker engine
  • Time-travel debugging (TTD) snapshots
  • Solver + emulator backed HIR verification
  • Symbolic equivalence checking

Automation & AI

  • Multi-provider AI agent pipeline
  • Rhai-based binary automation scripting
  • Quality lanes and regression tracking
  • Plugin runtime facade

Interfaces

fission-benchmark

Reproducible benchmark suite for decompiler quality evaluation.

  • Source-semantic correctness scoring against real binaries
  • Ghidra comparison lane
  • Docker-based reproducible runner
  • Public results dashboard

Principles

  • Correctness before presentation — semantic evidence first
  • Reproducibility by default — verifiable builds and results
  • Transparent evaluation — failures stay visible
  • Measured quality claims — no estimates as evidence
  • Open development — decisions and limitations documented publicly
