OSX/Machook, more commonly known as OSX/WireLurker, is malware distributed with hundreds of pirated OS X apps in China. Once installed on a target computer, it is capable of spreading to iOS devices connected to the infected Mac. It communicates with a command and control (C2) server and collects information about users and their connected devices. It was discovered by PaloAlto Networks in November 2014, and traced to infected applications available in the pirated app store as early as March, 2014 [1].
