Tweets at Google, Bing and Yahoo feature spam and malware risk

As Google, Yahoo and Bing has added real-time search features to their search query results the risk of spam and malicious links increases significantly, note security researchers. As tweets and other postings from popular social networking sites like Twitter and Facebook become part of the search engines it would be harder for the Google and other to filter fake destinations.

"This is just going to amplify the bad effects and make it easier for spammers and hackers to get their stuff to the top of search results," says Michael Greene, security analyst at PC Tools.

While Google and other search engines are using sophisticated systems to filter and prevent malicious links in the search results still they can fail when the link comes in the tweet posted by cyber criminals on Twitter. It's simple to attach spam or a link to a corrupted website, says Danny Sullivan, editor in chief of SearchEngineLand.com. Tainted posts moving quickly and intermittently into search results could be very hard to filter. "It's an entirely new cat-and-mouse game," says Sullivan.

"Even if the initial barriers work, don't expect clean results," says Roel Schowenberg, senior researcher at Kaspersky Lab. "It's likely cybercriminals will find ways around them."
