fuzzing-obstacles
The agent patches the system under test (SUT) to overcome common fuzzing obstacles using conditional compilation. It bypasses checksum and hash verification, replaces non-deterministic PRNG seeding with fixed seeds, skips complex multi-stage validation, and provides safe default values to prevent false positives. The agent uses FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION in C/C++ and cfg!(fuzzing) in Rust to ensure patches apply only during fuzzing builds. It applies this technique when coverage reports reveal unreachable code behind checksums, cryptographic signatures, time-seeded random state, or expensive validation logic that blocks fuzzer exploration of deeper code paths in libFuzzer, AFL++, honggfuzz, cargo-fuzz, and LibAFL targets.
