Abstract
A system facilitates detection of malicious properties of software packages. A generic application which comprises known functionality into which a software package has been included is analyzed through a static analysis and/or dynamic analysis, which is performed based on executing the generic application in a controlled environment. The static analysis and/or dynamic analysis are performed to determine whether one or more properties associated with the software package comprise deviations from the known behavior of the generic application. Behavior deviations identified based on the static and/or dynamic analysis are associated with a score. An aggregate score is calculated for the software package based on the scores which have been assigned to the identified behavior deviations and may be adjusted based on a reputation multiplier determined based on metadata of the software package. If the aggregate score of the software package exceeds a score threshold, the software package is flagged as malicious.
