Title: Various iOS Apps Found to be Malicious (a.k.a. XcodeGhost)
Description: Researchers at Palo Alto Networks have issued an advisory
warning users of several malicious iOS apps that have been found in the
App Store. The apps were found to have been compiled using a tampered
version of Xcode hosted on non-Apple servers in China and successfully
submitted to the App Store. Malicious versions of Xcode operated by
inserting malicious code into the app alongside the actual application
code during compilation.
