  • Patent number: 12141279
    Abstract: In a backdoor inspection apparatus, a static analysis unit executes static analysis processing for a backdoor on each code block included in target software to be inspected to thereby specify a first code block and a condition, the first code possibly being the backdoor and the first code block being executed under the condition. Next, the static analysis unit outputs the target software to which first information indicating the specified first code block is added and second information indicating the specified condition to a dynamic analysis unit. The dynamic analysis unit controls dynamic analysis processing for the backdoor performed on the target software to which the first information is added based on the first information and the second information.
