Abstract

The invention discloses a method for detecting abnormal data. The method comprises the steps of obtaining behavior data of each dimension in a plurality of dimensions of a to-be-detected file; determining portrait data of each dimension according to the behavior data of each dimension, wherein the portrait data of each dimension comprises program information of the to-be-detected file in the dimension; comparing the program information of each dimension in the to-be-detected file with established standard program detection information, thereby determining an offset of the program information of each dimension; and determining whether an abnormal program exists in the to-be-detected file or not according to the offset of the program information of each dimension. An embodiment of the invention further provides a corresponding apparatus. According to the technical scheme, whether the abnormal program exists in the file or not can be detected through the offset, so that the accuracy of anomaly detection is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method and device for abnormal data detection. Background technique [0002] With the rapid development of the Internet, there are more and more network attacks. In network attacks, hackers usually spread malicious programs written with attack intentions to the network, for example: embedded in some videos or files, once the user clicks Corresponding to the video or file implanted with a malicious program, the user's terminal will be implanted with the malicious program, thereby causing the user's terminal to be poisoned or information stolen. [0003] In the prior art, there are also some detection technologies for malicious programs to prevent these malicious programs, for example, the detection of malicious programs is realized by detecting program signatures and the like. [0004] However, there are more and more attack methods using normal programs t...
