401611 story Google Purges Thousands of Malware Sites 133 Posted by kdawson on Thursday November 29, 2007 @08:33AM from the just-in-time-for-holiday-shoppers dept. Stony Stevenson sends in word on the most massive "SEO poisoning" seen to date. The attack was directed at Google in particular and resulted in tens of thousands of Web pages hosting exploits showing up on the first page of Google searches for thousands of common terms (PDF). Sunbelt Software blogged about the attack on Monday after investigating it for months. By Wednesday Google had removed tens of thousands of malware-hosting pages from its index.
