Here are some interesting facts regarding WireLurker:

  • Largest malware to rely on repackaged OS X applications
  • It can automate the generation of malicious iOS applications
  • It can infect iOS applications in a manner similar to a virus
  • It can install third-party applications on all non-jailbroken devices.

So how does WireLurker work?

  • The first step is for WireLurker to infect an OS X system.
  • Once infected, WireLurker hides in the background and looks for an iOS device to connect
  • Once connected, it installs third-party software to the iOS device

What makes WireLurker extremely dangerous is that it can impact both jailbroken as well as non-jailbroken iOS devices.  It is a serious threat because it requests updates frequently from servers used by the attackers, making it more difficult to thwart once users have been affected.
