Malicious domain name detection method and device, electronic equipment and storage medium

The invention discloses a malicious domain name detection method and device, belongs to the technical field of network security, and is used for improving malicious domain name detection accuracy and reliability. The method comprises the following steps: according to domain name association data, obtaining a given malicious domain name and a to-be-detected domain name, and respective preset domain name features of the given malicious domain name and the to-be-detected domain name; acquiring a malicious score of the domain name to be detected according to a preset domain name feature and a given malicious domain name; inputting the malicious score and the preset domain name feature into a pre-trained long short-term memory network to obtain a hidden layer feature output by the long short-term memory network after feature coding is carried out on the current input; and inputting the malicious score, the preset domain name feature and the hidden layer feature into a pre-trained malicious domain name detection mo
