Apple To Randomize Device MAC Addresses In iOS8 For Better Network Security And Privacy

While no operating system is foolproof, iOS has been relatively exploit-free given the attention that's on it. And with the impending launch of iOS 8 this fall, Apple's ratcheting things up in a bid to add even more user privacy -- something that is becoming more of a foreign concept as advertisements grow and users become the product. With iOS 8, Apple will eliminate the unique device number that marketing clients and app devs have used to track users and their usage.


Essentially, iOS 8 will generate a random MAC address while scanning for a Wi-Fi network, which means that companies collecting that data won't be able to align things as they have before to track your hops around the Internet. In iOS 7, Apple bars app developers from using MAC addresses to track the quantity of people that have installed their apps, but iOS 8 takes it a step further. As Apple puts it: "The MAC address used for Wi-Fi scans may not always be the device’s real (universal) address."

It sounds minor in the grand scheme of things, but it's a pretty meaningful step for privacy, and we're hoping that other mobile OS providers follow suit.

Actually this is pretty big as it isn't common practice to have a changing MAC address, in fact I have never heard of a MAC address changing on a device before. A question I have is about IT security; As an IT Admin how would I block network access to a specific device if the MAC address changes? As it is right now I block the MAC address to band a certain device.

Mac address are hard coded, one good thing about changing mac address is that like IP addresses it will always change so it would never hold up in court anymore :P

wot, you work in IT and haven't seen (the ease of) MAC cloning? WRT54G "OS" replacements probably brought it into the mainstream... i use it on pfSense, myself. i'm pretty sure you can do it easily in Linux; and a quick google search seems to indicate that it's easy in Windows, too. and if not, you can just make a Virtualbox and proxy traffic thru whatever OS you want in there...

More nightmare for administrators.

Its also a bad thing if you lock down your WiFi by MAC address.

Been cloning/changing MAC addresses since the early days of the internet., in Windows its a registry entry and there are tools available & some network drivers have it built in, on the mac/linux avariation of  ifconfig/macchanger/uproute2 as root should do the trick. There are tools for most of the mobile platforms, I even had a tool that worked with Jailbroken iDevices.
