A vulnerability in the Apple iOS software has been uncovered that allows an attacker to substitute malware for a legitimate iOS app under a limited set of circumstances. Please be sure to follow the following guidelines:
a. Don’t install apps from third-party sources other than Apple’s official App Store.
b. Don’t click “Install” on a pop-up from a third-party web page, no matter what the pop-up says about the app. The pop-up can show attractive app titles crafted by the attacker.
c. When opening an app, if iOS shows an alert with “Untrusted App Developer”, click on “Don’t Trust” and uninstall the app immediately.
