Problems solved by technology

However, for scenarios where processes such as network services do not exit, such as network services running on Internet of Things (IoT) devices, the Fuzzing process cannot perceive whether it has reached the end of the operation, resulting in a fuzzing that cannot be ended quickly, thus Makes the entire Fuzzing process slower

Abstract

The invention discloses a method and device for dynamically determining an end block, and the method comprises the steps: carrying out the pre-fuzzing testing of a to-be-tested binary program based on each test case in all test cases, and recording the end block in an end block list; and in response to a message of ending the pre-fuzzing test, performing fuzzing test on the to-be-tested binary program according to a preset rule on the basis of a variation case after variation of the test case, the preset rule being used for dynamically determining an ending block and updating an ending block list, and performing module test on the basis of the updated ending block list. According to the method, the object of Fuzzing can be broadened for scenes such as network services on IoT (Internet of Things) equipment in which running cannot be ended, and guidance is provided for variation of test examples in the Fuzzing process in cooperation with a discovery mechanism of End Block, so that the speed of discovery of binary program vulnerabilities on the IoT equipment and the like is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for dynamically determining an end block (End Block). Background technique [0002] Fuzzing is a method of discovering software vulnerabilities by providing unexpected inputs to the target system and monitoring abnormal results. It is widely used by major software manufacturers to mine vulnerabilities in their own products, thereby reducing vulnerabilities in products. . At present, Fuzzing technology is usually applied in ordinary service processes or various module components. The completion of their software operation can be used as a sign of the end of Fuzzing, which is convenient for Fuzzing to work quickly. However, for scenarios where processes such as network services do not exit, such as network services running on Internet of Things (IoT) devices, the Fuzzing process cannot perceive whether it has reached the end of the operation, result...
