The goal is to provide a tool that uses fuzzing (or attack injection) to search for vulnerabilities in smart contracts by doing input injection. It selectively 'un-fuzzes' portions of a fuzzed file that is known to cause a crash, re-launches the targeted application, and sees if it still crashes. Grab the PDF file 2. These tests verify whether the tested system behaves correctly and reliably as per functio-nal requirements, and whether it goes into safe mode in case of a malfunction. Overall, using neural fuzzing outperformed traditional AFL in every instance except the PDF case, where we suspect the large size of the PDF files incurs noticeable overhead when querying the neural model.
