Stealth MAC is an absolute necessity if you’re going to be doing anything subversive from your iPod/iPhone every network enabled device has what is known as a MAC address which is a unique identifier that’s assigned to the network adapter by the manufacturer. These are supposed to be globally unique ( but that’s not always the case) and normally the first three pairs of numbers/letters identify the hardware manufacturer. This is terrible if we’re planning on doing something subversive on a network as it’s a digital footprint of our activities.
Stealth MAC allows us to change the MAC address of the iPhone/iPod’s WiFi adapter. The best part is that it’s really easy to use. Simply edit the file “/etc/stealthmac” on your iPod/iPhone. The file should look something like this
#Replace the following value with your desired MAC address for the wireless interface 00:1f:5b:86:3f:d8
As it says just replace the mac address in the file with the one you want to pretend to be. I very highly recommend changing the first three pairs as those are what identify your iPod/iPhone as an Apple device. People can use tools to like http://coffer.com/mac_find/ to find out what manufacturer the MAC is registered to. The MAC address is a HEX address so when creating a false one only use the numbers 0-9 and the letters a through f.
Another way switching your MAC address can be useful is in hijacking someones session on a WiFi hotspot. If you can identify the MAC address of a paid user on a pay WiFi hot spot you can often change your MAC address to theirs and get some free Internet. although it can be a bit spotty if they’re trying to use it at the same time as you.
