CHAMELEONChameleon

The Chameleon botnet is a botnet that was discovered on February 28, 2013 by the security research firm, spider.io. It involved the infection of more than 120,000 computers and generated, on average, 6 million US dollars per month from advertising traffic. This traffic was generated on infected systems and looked to advertising parties as regular end users which browsed the Web, because of which it was seen as legitimate web traffic. The affected computers were all Windows PCs with the majority being private PCs (residential systems).
