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
- Support for *SAN, CMPLOG, CMPCOV binaries
Other features:
- Add Tmux option to automatically create an appropriate layout for all runners

TODO

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 /tmp/test_bins/target -s /tmp/test_bins/target_asan -c /tmp/test_bins/target_cmplog -l /tmp/test_bins/target_cmpcov -n 16 -i /tmp/seed_corpus -o /tmp/afl_out -x /tmp/fuzzing.dict -m "custom_fuzz_session"

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