Abstract

The invention discloses a malicious software detection method. The detection method comprises the steps that Client Hello information sent by a client to a server is acquired; wherein the Client Helloinformation comprises a TLS protocol version of the client, a password suite, an extension item and key encryption information; according to the Client Hello information, TLS fingerprint informationof the client side is generated; judging whether a malicious fingerprint feature library comprises TLS fingerprint information of the client or not; and if so, judging that malicious software is detected. The method can improve the identification accuracy of malicious software. The invention further discloses a malicious software detection device, a storage medium and electronic equipment, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of network security, and in particular to a malware detection method and device, an electronic device and a storage medium. Background technique [0002] In the field of network threat intelligence applications, malware is usually identified based on IoC (Indicators of Compromise, intrusion indicators), but this IoC-based malware identification method often needs to cooperate with file hash value (hash), domain name, Internet protocol address (Internet Protocol Address, IP address), Uniform Resource Identifier (Uniform Resource Identifier, URI) path, Hypertext Transfer Protocol User-Agent (HTTP User-Agent), and even network communication messages and many other information. In order to hide malicious communication in legitimate communication traffic and increase the difficulty of detection, more and more malware uses changing domain names, IP addresses and encrypted network traffic to disguise, so ...
