Abstract

The invention provides a mail metadata processing method and device, a storage medium and an electronic device, and the method comprises the steps: collecting a mail sample; identifying the file typeof the mail sample by adopting a network ontology language OWL rule; extracting metadata of the mail sample according to the file type, and setting a metadata tag; and extracting data information froma user file according to the metadata tag, and judging whether the user file is a threat file for identifying an advanced persistent threat APT type according to the data information. According to the method and the device, the technical problem of low efficiency of extracting the metadata of the mail sample in the prior art is solved.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method and device for processing mail metadata, a storage medium, and an electronic device. Background technique [0002] A network attack is an attack on an electronic device by a hacker or a Trojan horse, which causes huge losses to users by stealing files. [0003] When tracking and discovering advanced persistent threat (Advanced Persistent Threat, APT) groups, context analysis is mainly based on malicious files, phishing emails and other attacks in network transmission. Attackers use malicious programs to intrude and control networks and information systems to steal sensitive data and damage systems and network environments. It is urgent to improve the detection rate and batch analysis capabilities of malicious samples spread in enterprise networks. [0004] In related technologies, in the field of computer security, network attacks are becoming more and more specialized a...
