22 May 2007 One in ten websites have a dark side
Research by the search engine found pages on websites were capable of launching so-called ‘drive-by downloads’ which are capable of installing programs such as spyware. It found the ‘drive-by downloads’ when it surveyed billions of websites and subjecting 4.5 million pages to what it called in-depth analysis. Of those, around 450,000 had the programs which are becoming an increasingly common way to infect a computer or steal sensitive information. The vast majority of ‘drive-by downloads’ exploit vulnerabilities in Microsoft's Internet Explorer browser to install themselves when a potential victim visits a booby-trapped website. Some downloads, such as those that alter bookmarks, install unwanted toolbars or change the start page of a browser, are an annoyance. But, increasingly, criminals are using ‘drive-by downloads’ to install keyloggers that steal login and password information. Other pieces of malicious code hijack a computer turning it into a bot (a remotely controlled PC). Google is now in the process of mapping the threat and, as part of its place in the StopBadware coalition, is already warning users about visiting potentially harmful websites. |
