Guides fuzz testing by providing domain-specific tokens to reach deeper code paths in parsers and protocols.
This skill provides a comprehensive methodology for creating and implementing fuzzing dictionaries to enhance automated security testing. By supplying known keywords, magic numbers, and protocol commands, it helps fuzzers like libFuzzer and AFL++ bypass initial validation logic and explore complex code branches in file formats, network protocols, and configuration parsers. It includes practical patterns for common formats and troubleshooting steps for improving testing coverage.
