Codebases often contain anti-fuzzing patterns that prevent effective coverage. Checksums, global state (like time-seeded PRNGs), and validation checks can block the fuzzer from exploring deeper code paths. This technique shows how to patch your System Under Test (SUT) to bypass these obstacles during fuzzing while preserving production behavior.

Many real-world programs were not designed with fuzzing in mind. They may:

The solution is conditional compilation: modify code behavior during fuzzing builds while keeping production code unchanged.
