# Dynamic Analysis Fuzzer
|
|
This fuzzer is to show how you can collect runtime analysis information during fuzzing using LibAFL. We use the Little-CMS project for the example.
|
|
First, this fuzzer requires `nlohmann-json3-dev` to work.
|
|
|
|
To run the fuzzer,
|
|
0. Compile the fuzzer with `cargo build --release`
|
|
1. `mkdir analysis` and run `build.sh`. This will compile Little-CMS to extract the analysis information and generate a json file for each module.
|
|
2. run `python3 concatenator.py analysis`. This will concatenate all the json into one single file. This json file maps a function id to its analysis information.
|
|
3. Compile the fuzzer with `cargo make fuzzer`. This will instrument the fuzzer at every function entry point. Therefore, whenever we reach the entry of any function, we
|
|
can log its id and logs what functions we executed.
|
|
4. Run the fuzzer `RUST_LOG=info ./fuzzer --input ./corpus --output ./out`. You'll see a stream of analysis data |
