haruspex

"Hacking is the discipline of questioning all your assumptions all of the time."

-- Dave Aitel

Haruspex is a blazing fast IDA Pro headless plugin that extracts pseudo-code generated by IDA Pro's decompiler in a format that should be suitable to be imported into an IDE or parsed by static analysis tools such as Semgrep, weggli, or oneiromancer.

Features

• Blazing fast, headless user experience courtesy of IDA Pro 9 and Binarly's idalib Rust bindings.
• Support for binary targets for any architecture implemented by IDA Pro's Hex-Rays decompiler.
• Pseudo-code of each function is stored in a separated file in the output directory for easy inspection.
• External crates can invoke decompile_to_file to decompile a function and save its pseudo-code to disk.

Installing

The easiest way to get the latest release is via crates.io:

1. Download, install, and configure IDA Pro (see https://hex-rays.com/ida-pro).
2. Download and extract the IDA SDK (see https://docs.hex-rays.com/developer-guide).
3. Install haruspex as follows:

   $ export IDASDKDIR=/path/to/idasdk
   $ export IDADIR=/path/to/ida # if not set, the build script will check common locations
   $ cargo install haruspex # or run cargo add haruspex to install as a library

Note: in addition to the latest IDA SDK and IDA Pro itself, a recent version of LLVM/Clang is required (see idalib documentation).

Compiling

Alternatively, you can build from source:

1. Download, install, and configure IDA Pro (see https://hex-rays.com/ida-pro).
2. Download and extract the IDA SDK (see https://docs.hex-rays.com/developer-guide).
3. Compile haruspex as follows:

   $ git clone --depth 1 https://github.com/0xdea/haruspex
   $ cd haruspex
   $ export IDASDKDIR=/path/to/idasdk # or edit .cargo/config.toml
   $ export IDADIR=/path/to/ida # if not set, the build script will check common locations
   $ cargo build --release

Note: in addition to the latest IDA SDK and IDA Pro itself, a recent version of LLVM/Clang is required (see idalib documentation).

Usage

1. Make sure IDA Pro is properly configured with a valid license.
2. Run haruspex as follows:

   $ haruspex <binary_file>

3. Find the extracted pseudo-code of each decompiled function in the binary_file.dec directory:

   $ vim <binary_file>.dec
   $ code <binary_file>.dec
