“How often do you open 20 or 30 browser windows to different sites simultaneously? Computers infected with a number of different click-fraud malware families may generate noisy volumes of Web traffic in short bursts. Or, for instance, on a corporate network with a locked-down software policy, where everyone is supposed to be using one type of browser, an analyst might see a Web session in which the user-agent string which identifies the browser to the Web server indicates the use of a browser that’s far removed from the standard corporate image, or maybe a version that doesn’t even exist.” Andrew Brandt – Principal Researcher at Sophos
