A decade ago, social media didn’t exist. By 2008, Facebook had become popular enough to attract the attention of malware authors. One of them created an annoying cross-platform worm that targets Windows, Mac OS X, and even Linux. The worm gathered login details, built a botnet, and made money by installing additional malware. It also used a common social engineering trick, trying to convince potential victims that they needed to install a Flash Player update that was actually the malicious payload.
Facebook took down the network by decapitating its control servers in early 2011.
All pretty routine stuff, by modern standards, but the twist is that this gang was unmasked after several years of making Facebook users’ lives miserable. ZDNet blogger Dancho Danchev published his own takedown of the botnet master on January 9, 2012, complete with embarrassing personal photos. Facebook publicly revealed the identities of the entire gang the following week.
