Substrate WASM fuzzer

Community project for fuzzing WASM in Substrate.

Attack model: Attacker payload -> TX -> WASM Execution

Example

./wasmfuzz -f -n -c <contract-file.wasm> -i

Dev tasks

  • Fuzzer logic/engine
  • Fuzzer input

Good question

Why don't we just use AFL? We could inject from TX entry func... https://github.com/rust-fuzz/afl.rs https://aflplus.plus/
