Diagnosing Disassembly with Dr. Disassembler

This repository contains a prototype of using Datalog for disassembly, described in this blog post (PDF). This disassembler takes a portfolio approach to disassembly: it supports multiple binary parser frontends, and multiple instruction decoder frontends.

The core of the disassembly algorithm is implemented in Datalog, which is compiled to Python. We have included the auto-generated code in here. This prototype does not scale well to large binaries as Python is very slow.

Installation

pip3 install --index-url https://lief.quarkslab.com/packages lief==0.11.0.dev0
python3 setup.py install

Usage guide

Changing the binary parser

Dr. Disassembler (DDS) allows one to switch out the binary parser that is used. DDS supports three binary parsers: LIEF, Binary Ninja, and IDA Pro.

LIEF

python3 -m dds.__main__ --binary examples/helloworld/helloworld.elf.x86_64.nopie \
    --binary_parser lief --instruction_decoder capstone --workspace_dir dds_tmp

Binary Ninja

python3 -m dds.__main__ --binary examples/helloworld/helloworld.elf.x86_64.nopie \
    --binary_parser binja --instruction_decoder capstone --workspace_dir dds_tmp

IDA Pro

python3 -m dds.__main__ --binary examples/helloworld/helloworld.elf.x86_64.nopie \
    --binary_parser ida --ida_path /Users/$USER/Applications/IDA\ Pro\ 7.5/idabin/idat64 \
    --instruction_decoder capstone --workspace_dir dds_tmp

Note that --ida_stdout_path and --ida_stderr_path are also supported.

Changing the instruction decoder

The instruction decoder can also be changed, by changing --instruction_decoder. For example, if you are using --binary_parser binja, then you should probably also use --instruction_decoder binja.
