Problems solved by technology

[0004] However, hackers can bypass the above detection methods by means of dialing, proxy IP, etc., and judging the IP segment is also easy to misjudge the normal account under the IP segment (such as other user accounts in the subnet under the same gateway) as Abnormal accounts, making the judgment accuracy of abnormal accounts not high

Abstract

The invention provides an abnormal account detection method. The method includes the following steps that: an uploaded service request is received, and an initiating account corresponding to the service request is searched; corresponding request parameters are extracted from the service request, wherein the request parameters comprise at least one behavior tag, and the tag types of the behavior tags include at least one kind of type selected from service identifier, time interval, IP address, initiating position, system type, version identifier, service data numerical interval or related account; statistics information corresponding to the initiating account is updated according to the request parameters, wherein the statistics information includes the number of the times of visits corresponding to each behavior tag; and whether the initiating account is an abnormal account can be judged according to the statistics information. The invention also provides an abnormal account detection device. With the above abnormal account detection method and device adopted, accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for detecting an abnormal account. Background technique [0002] At present, account password leakage on the Internet is very serious, and hacking incidents often occur. After stealing account passwords, hackers usually send pornographic advertisements, scams, virus links and other messages to friends corresponding to the stolen account, disrupting the daily life of users. Therefore, it is necessary to detect such abnormal accounts. [0003] The method for detecting abnormal accounts in the traditional technology is usually based on the IP segment, and judges whether the IP segment is occupied by account hackers by counting the distribution of received command types, so as to determine the account under the IP segment as an abnormal account. [0004] However, hackers can bypass the above detection methods by means of dialing, proxy IP, etc., and judg...
