Yi-Min Wang, director of network research and network management research at Microsoft Research, explains: " Instead of commenting on blogs or forums, spreaders will send the URL to the link. Linking junk sites to it Because their frequency of occurrence is too much on a legitimate page, Google's search engine, Yahoo or MSN will save these URLs in the index and display them on the results table. " .
Tool to eliminate garbage web from search sources Picture 1 The tool that Microsoft designed uses a search engine on forums or spam, identifies spam URLs and deletes them before being indexed by search engines. "The Strider Search Defender recognizes where a legitimate URL is, what a garbage address is ," Wang said.
In case the dispenser uses "open domain" (domain doorway - domain used to rank keywords in search engines, acts as a gateway through the main domain) to build a spam page, the tool will determine The domain is exploited and reported to the administrator. This open domain is a legitimate URL but can be used by spammers to build spam pages that look like real websites and trick users and search engines.
Wang said free web sites such as MySpace or Google BlogSpot can use Microsoft methods to determine who spreaders are using their site as an open domain. Users should close pop-up pages that they have never visited or used.
