Flash wrongly sited as security risk

HTML5 Ads Aren't That Safe Compared To Flash, Experts Say (softpedia.com)34

An anonymous reader writes:[Softpedia reports:] "A study from GeoEdge (PDF), an ad scanning vendor, reveals that Flash has been wrongly accused as the root cause of today's malvertising campaigns, but in reality, switching to HTML5 ads won't safeguard users from attacks because the vulnerabilities are in the ad platforms and advertising standards themselves. The company argues that for video ads, the primary root of malvertising is the VAST and VPAID advertising standards. VAST and VPAID are the rules of the game when it comes to online video advertising, defining the road an ad needs to take from the ad's creator to the user's browser. Even if the ad is Flash or HTML5, there are critical points in this ad delivery path where ad creators can alter the ad via JavaScript injections. These same critical points are also there so advertisers or ad networks can feed JavaScript code that fingerprints and tracks users." The real culprit is the ability to send JavaScript code at runtime, and not if the ad is a Flash object, an image or a block of HTML(5) code.
