Fuzzers for coverage
WebJul 10, 2024 · the fuzzer computes a score from the reported coverage, and uses it to prioritize the interesting mutated tests and remove the redundant ones For example, let's say the input test is "hello". Fuzzer may mutate it to a number of tests, for example: "hEllo" (bit flip), "hXello" (byte insertion), "hllo" (byte deletion).

Fuzzers for coverage
Did you know?
Webfuzzers always rely on some form of heuristics to guide their exploration. The most popular of these strategies is, by far, Coverage-Guided Fuzzing (CGF), in which the fuzzer selects inputs that try to increase some coverage metric computed over program code—typically, the number of unique edges in the control flow graph. WebJul 29, 2024 · Dumb fuzzers produce completely random input that does not necessarily match the shape of the expected input. Lack of built-in intelligence about the software it’s fuzzing makes this type of fuzzer a …
