afl_runner 0.1.6

AFLRunner

AFL_Runner is a simple CLI tool to make running efficient multi-core AFLPlusPlus campaigns easier. The default configuration is based on the section Using multiple cores of the official documentation.

The current implementation only accepts a small subset of AFLPlusPlus flags for some custom configuration.

Usage

You can compile it yourself via:

git clone https://github.com/0xricksanchez/AFL_Runner.git alfrunner
cd aflrunner
cargo build --release
./target/release/afl_runner --help

Alternatively you can install via crates.io:

cargo install afl_runner
afl-runner --help

Features

The tools allows for setting the most necessary AFLPlusPlus flags and mimics to some degree the same syntax as AFLplusplus for these things:

• Supported AFLplusplus flags:

  • corpus directory
  • output directory
  • dictionary file
  • Custom afl-fuzz binary path for all instances
  • Supply arguments to target binary (including @@)
  • Amount of runner commands to generate

• Other features:

  • Add Tmux option to automatically create an appropriate layout for all runners

TODO

• Add LAF-Intel/CMPCOV option
• Add remote option.
• Add more sensible defaults for other options
• Add more configuration options
• Allow AFLPlusPlus forks to be used on some amount of runners

Showcase

If you generate your AFL++ commands it may look similar to the following below.

afl_runner -t test_bins/target -s test_bins/target_asan -c test_bins/target_cmplog -n 8 -i /tmp/seed_corpus -o /tmp/afl_out -x /tmp/fuzzing.dict -m "custom_fuzz_session" --dry-run -- 'arg1 arg2 --arg3 --arg4 @@'

Note: Supplying the sanitizer, CMPLOG, or CMPCOV binaries are optional and if omitted all invocations just contain the instrumented target instead.
