McAfee Labs has discovered that banking malware Pinkslipbot (also known as QakBot/QBot) has used infected machines as control servers since April 2016, even after its capability to steal personal and financial data from the infected machine has been removed by a security product. These include home users whose computers are usually behind a network address translation router. To do so, Pinkslipbot uses universal plug and play (UPnP) to open ports, allowing incoming connections from anyone on the Internet to communicate with the infected machine.
