Abstract: A method for security protection of account information is provided, where the method includes: detecting an account input event on an accessed web page; determining, when the account input event is detected, whether a URL of the accessed web page exists in a preset secure URL list; calculating, if the URL of the accessed web page does not exist in the secure URL list, a page similarity between the accessed web page and a preset real web page according to the URL and/or web page content of the accessed web page; and determining, according to the page similarity, whether the accessed web page has a security risk, and if yes, displaying an account security risk alert. The method preventing a user from being induced by a malicious website to input an account and a password. A system for security protection of account information is further provided.

Abstract: Embodiments provide a malicious website address prompt method and a router. A router acquires a target website address in a network access request in access of a user terminal, determines whether the target website address is a malicious website address, and if determining that the target website address is a malicious web site address, sends prompt information of intercepting the target website address to the user terminal. Malicious web site address intercept software does not need to be installed in the user terminal, and the security of Internet surfing of a user is improved in a case in which the malicious website address intercept software cannot be installed in the user terminal or is not installed by the user.

Abstract: Examples of the present disclosure provide a method and device for detecting a malicious URL, the method includes: a URL detection request is received, contents of a page addressed by a URL in the URL detection request are analyzed, and it is determined that whether the page is a non-text page; when the page is a non-text page, a page image of the page, which is displayed in a browser and addressed by the URL in the URL detection request, is obtained, image detection is performed on the page image, and a page attribute of the URL in the URL detection request is obtained, whether the URL is a malicious URL is determined based on the page attribute of the URL in the URL detection request.

Abstract: A method for monitoring a malicious attribute of a webpage is disclosed. The method includes the following steps: acquiring webpage query requests submitted by a plurality of clients; crawling a webpage based on the webpage query requests and acquiring crawled webpage contents; counting up a referenced value of a URL based on the webpage contents; calling a predetermined detection program to detect a malicious attribute of the URL based on the a referenced value of the URL. The accuracy of detection can be improved by using the method for monitoring a malicious attribute of a webpage provided in the present disclosure. Furthermore, a system for monitoring a malicious attribute of a webpage is further disclosed.

Abstract: According to an example, an address of a web page to be identified is obtained, data of the web page from the address of the web page is crawled, the data of the web page is parsed and data for identification is obtained. The web page determined as malicious information according to the data for the identification, and the malicious information is intercepted.
