'War texting' hacks car systems and possibly much more
Remotely start cars, attack SCADA, through GSM
Customer Success Testimonial: Recovery is Everything
Software that allows drivers to remotely unlock and start automobiles using cell phones is vulnerable to hacks that allow attackers to do the same thing, sometimes from thousands of miles away, it was widely reported Wednesday.
The exploit affecting an undisclosed product used to remotely control cars was developed by iSec researchers Don Bailey and Matthew Solnik by reverse engineering the GSM, or Global System for Mobile Communications, technology it relies on.
By setting up their own, private GSM network and then closely monitoring it, they were able to figure out the codes needed to send rogue commands to cars that relied on the system. They used a laptop to recreate the messages, a technique they dubbed "war texting."
While the hack raises obvious concerns for users of OnStar RemoteLink and other systems for remotely controlling automobiles, it could pose even more of a threat to operators of SCADA, or supervisory control and data acquisition, systems used to control valves, gears, and other physical processes in industrial plants and factories, Bailey said.
Many industrial control systems also rely on GSM networks to send and receive commands. With the declining cost of operating ad-hoc GSM networks, it could become increasingly easy to penetrate these systems and defeat the security-through-obscurity protections they rely on.
The researchers are scheduled to present their findings during a talk titled War Texting: Identifying and Interacting with Devices on the Telephone Network at next week's Black Hat security conference in Las Vegas.

Software that allows drivers to remotely unlock and start automobiles using cell phones
WTF? What the hell is wrong with a bloody *KEY*???
In any case, why on earth would you want to be able to unlock and start your car from a distance apart from to make life easier for the thief who'll say "thanks for the car, bye bye!"? (There's also the fact that, in England, it's an offence to leave a vehicle unattended with the engine running...)
You get a thief and an idiot tailgater with one stone...
...I can live with that.
Multiple messages
...thus multiplying the cost of each control message transmitted by 3 or 4 times. In other words, the kind of thing that the devs would have thought of and the beancounters would have rejected...
