Lenovo will be rolling out software to allow remote disable of laptops via the WAN card. Apparently you'll be able to send a text message to the laptop from any of ten phones that will disable it immediately if it is on, or the next time that it is turned on if off. There also appears to be a provision to unlock it if it is recovered. Also mentioned is a similar service from Dell.

Lenovo plans to drive notebook thieves crazy by introducing an all-new security feature expected to fly by the first quarter of 2009. Called the Lenovo Remote Disable Feature, it will enable laptop owners to remotely render their devices useless with just a single text. The system is targeted at consumers who are worried about their laptops getting stolen.

Ok, so what are we going to call the act of driving around with a modified cellular device and disabling people's laptops?    Grin

It's brief but it's out there:

If anyone wants to improve on it, feel free.

One problem you would run into Warzapping is that according to the article you have to preset which phone numbers can send the signal so you would have to spoof that.  Also I am guessing that the "message" you have to send is not standard but a customized "password/phrase" each individual user creates.  It would be really fun to play with though.

Definitely worth a bit of experimentation. As it so happens, I should have a Lenovo laptop arriving in the next week or so  Grin.

If its looking for a particular phone number to be sending the disable signal, it might be spoofable, depending on what exactly it's looking for. If it's something simple like caller ID (seems unlikely), then it should be really simple to fake.

Warzapping could also apply to certain mobile phones. I've seen a feature on some Symbian phones to lock the phone on reciept of a text message with a predetermined keyword. As far as I can see SMS message can originate from anywhere. So spam a whole load of phones with the message 'lock' and see how far you get  Grin

falcom samba 75 gprs usb modems (£180) can record everything received from a txt. including the additional info, then just clone it.  Smiley

good luck.

I'm curious to see what other devices have features like this. So far laptops, PDAs, phones, and vehicles.
