Abstract

The invention discloses a phishing mail detection method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of extracting target fields related to domain names in mail data to form a field set; extracting target domain names in the field set to form a domain name set, wherein the target domain names comprise first-level domain names and/or sub-domain names; calling a domain name spelling error correction model to process the target domain names in the domain name set, wherein the domain name spelling error correction model is generated by pre-training based on a spelling error correction algorithm and is used for outputting a corresponding correctly spelled domain name after a mistakenly spelled domain name is input; and judging a mail corresponding to the target domain name which enables the output of the domain name spelling error correction model to be not empty as a phishing mail. According to the invention, the pre-trained domain name spelling error correction model is utilized, the phishing mails disguised by adopting non-splicing confusion means can be effectively identified, the user account is effectively prevented from being damaged by the phishing mails, and the use safety of the mails is greatly improved.

Description

Technical field [0001] The present application relates to the field of network security testing, and Background technique [0002] With the development of network information technology, network security issues are also endless. Many illegal people implement their online criminal activities by sending malicious messages to users, such as stealing users, and control user's computers. [0003] Among them, fishing mail is very harmful to users, and a fishing technique for use often uses dangerous operations such as landing, transfer, download malicious attachments by imitating well-known domain names. Therefore, it is very important to effectively detect fishing emails to avoid corresponding losses. [0004] The current method of detecting fishing emails is primarily based on splicing confusion; the program can detect results after stitching with other strings, such as Google-Id.com, baidu-app.com, etc. However, for some non-spliced ​​phishing mail, the program is in powerless. For ...
