Flash-Based Malware Ad Sneaks Onto Legit Websites Via DoubleClick

A new malware ad has managed to sneak its way onto Doubleclick’s DART ad publishing system, which means it’s been showing up on several legitimate websites, including Major League Baseball, The Economist, and Canada.com. It doesn’t require user interaction to be triggered—as soon as it’s loaded into the page, it initiates the redirect, closes your browser window, and starts bullying you to install “anti-virus” software. It will even attempt to download a virus-laden .exe file, naturally.
