Abstract
A program analysis device (1001) includes: a flow length acquisition unit (1003) that acquires flow length information indicating a length of a processing flow to be analyzed that includes a sensitive operation defined by a predetermined start point and a predetermined end point in a program; and a score calculation unit (1004) that calculates a backdoor score indicating a possibility that the processing flow to be analyzed is a backdoor code based on the flow length information.
Claims15
A program analysis device comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire flow length information indicating a length of a processing flow to be analyzed including a sensitive operation defined by a predetermined start point and a predetermined end point in a program;
- and
- calculate a backdoor score indicating a possibility that the processing flow to be analyzed is a backdoor code based on the flow length information.
A program analysis method comprising:
- acquiring flow length information indicating a length of a processing flow to be analyzed including a sensitive operation defined by a predetermined start point and a predetermined end point in a program;
- and
- calculating a backdoor score indicating a possibility that the processing flow to be analyzed is a backdoor code based on the flow length information.
A non-transitory computer readable medium stored with a program for causing a computer to execute processes of:
- acquiring flow length information indicating a length of a processing flow to be analyzed including a sensitive operation defined by a predetermined start point and a predetermined end point in a program;
- and
- calculating a backdoor score indicating a possibility that the processing flow to be analyzed is a backdoor code based on the flow length information.
