New iOS threat can render your device unresponsive and forever useless.

New iOS threat can render your device unresponsive and forever useless.

If you use an Apple iPhone, iPad or other iDevice, now would be an excellent time to ensure that the machine is running the latest version of Apple’s mobile operating system — version 9.3.1. Failing to do so could expose your devices to automated threats capable of rendering them unresponsive and perhaps forever useless.

Reported earlier by respected security researcher Brian Krebs, Manually setting the date of your iPhone or iPad all the back to January. 1, 1970 will permanently brick the device (don’t try this at home, or against frenemies!).

Apple products like the iPad (and virtually all mass-market wireless devices) are designed to automatically connect to wireless networks they have seen before. They do this with a relatively weak level of authentication: If you connect to a network named “Hotspot” once, going forward your device may automatically connect to any open network that also happens to be called “Hotspot.”

For example, to use Starbuck’s free Wi-Fi service, you’ll have to connect to a network called “attwifi”. But once you’ve done that, you won’t ever have to manually connect to a network called “attwifi” ever again. The next time you visit a Starbucks, just pull out your iPad and the device automagically connects.

From an attacker’s perspective, this is a golden opportunity. Why? He only needs to advertise a fake open network called “attwifi” at a spot where large numbers of computer users are known to congregate. Using specialized hardware to amplify his Wi-Fi signal, he can force many users to connect to his (evil) “attwifi” hotspot. From there, he can attempt to inspect, modify or redirect any network traffic for any iPads or other devices that unwittingly connect to his evil network.
