Jerome Segura of the California software security firm announced in a company blog post that many of those ads (often featuring models wearing a bikini, at the most) in fact direct users to secondary sites that attempt to install malware on their computers - potentially resulting in identity theft or other kinds of infection. Since mainstream advertisers tend to avoid controversy, the Pirate Bay tends to attract malicious ones, and administrators have either failed to do their due diligence or simply ignored the risk. According to Alexa Internet rankings, the Pirate Bay is visited almost as often as the British Daily Mail tabloid and more often than Vimeo, Flickr and the New York Times. By linking to torrent files of copyright music, movies and other media content, it has become the 79th most visited websites in the U.S. The Pirate Bay is simultaneously one of the most popular websites online and one of the most notorious. The popular torrent site is filled with copyright TV and movies, but it also filled with ads that could fill a visitor's computer with malicious software, according to a new security study. Yet another reason to avoid Pirate Bay: malicious ads.
