The invention belongs to the technical field of computer network security, and particularly relates to a fuzzy test system and terminal equipment. The fuzzy test system provided by the embodiment of the invention can comprise a core fuzzy test engine, an exception detection engine and an exception report engine, wherein the core fuzzy test engine is used for generating a test vector input into a target test object; wherein the exception detection engine is used for detecting undefined and potential unsafe behaviors of the target test object; and the exception reporting engine is used for reporting all information related to the target test object when the target test object is exceptional. Compared with an existing fuzzy test which is only suitable for finding specific weaknesses in a specific tested system, the fuzzy test system provided by the invention has wider applicability.
