  • Publication number: 20180189481
    Abstract: A program file classification method, a program file classification apparatus, and a program file classification system, where the system sets an agent program in a client and a sandbox server to obtain behavior information corresponding to at least two behaviors executed by a program file at runtime. Each piece of behavior information includes a behavior identifier and a path related during execution of a corresponding behavior. A classification server performs normalization process on the path in each piece of behavior information, where the normalization process reduces path diversity, generates a feature vector according to at least two pieces of behavior information obtained after the path normalization process, and determines, according to the feature vector, a category to which the program file belongs. Because normalization process is performed on the path, randomness of a path obtained after the normalization process is reduced.
