Searching for Flash Player on Bing and Yahoo can lead to rogue pages distributing a hard-to-remove rootkit. The problem resides with the so-called sponsored results, the advertisements displayed at the top of search results for particular keywords. In September, GFI’s researchers reported a similar attack, which targeted keywords for Firefox, Skype and uTorrent. Google used to have similar problems, with cybercriminals regularly tricking its sales team into accepting rogue ads. Fortunately, the attacks detected so far have mainly relied on social engineering to infect users.”]
