Nearly two-thirds of all Internet traffic originates from non-human sources and 60% of them are malicious. This report comes from the bot-tracking firm Incapsula. We human surfers only make up 38.5%. But the report wasn’t all bad. Although there has been an overall growth in bot activity, Incapsula said that many of the traditional malicious uses of the bots has become less common. Well, that’s good. But why are bots so prevalent? Because they’re easy to build. So easy to build, one source said, that even a journalist that didn’t know code could pick up a $300 bot kit and get going.
