Abstract

The invention relates to a method and a device for detecting a Hosts file, which belong to the technical field of network security. The method comprises steps: the attribute information of the Hosts file is acquired, wherein the attribute information is used for indicating the corresponding relationship between each website in the Hosts file and an IP (Internet Protocol) address, the blank line number in the Hosts file and the data amount of the Hosts file; according to the attribute information, whether the Hosts file meets at least one selected from a first preset condition and a second preset condition is detected; and if yes, the website in the Hosts file is determined to have a hijacked risk, and on the basis of detecting whether the Hosts file contains the website in a preset website set and in combination of the corresponding relationship between each website in the Hosts file and the IP address, the blank line number and the data amount of the Hosts file, whether the website in the Hosts file has a hijacked risk is detected, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for detecting a Hosts file. Background technique [0002] At present, many virus programs can affect the normal network access of the browser by hijacking the URLs in the Hosts file. Therefore, detecting whether the website address in the Hosts file has the risk of being hijacked is an important means to ensure the security of the computer network. [0003] The existing technology mainly detects whether there is a hijacked website in the Hosts file through the cloud check detection method. Specifically, the cloud server collects and maintains a collection of URLs, which contain virus programs that may hijack URLs, usually websites with high versatility, such as train ticket buying websites, antivirus software official websites, and well-known websites. For anti-virus related websites, etc., when the terminal detects the Hosts file, it sends each URL...
