The vulnerability has been fixed.
Remember, a modern car isn't an automobile with a computer in it. It's a computer with four wheels and an engine. Actually, it's a distributed 20-400-computer system with four wheels and an engine.
As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.
Roughly three weeks later, there is a operation program available to crack ACBL hand records.
- Given three consecutive boards, all the remaining boards for that session can be determined.
- The program can be easily parallelized. This analysis can be finished while sessions are still running
this would permit the following type of attack:
- A confederate watch boards 1-3 of the USBF team trials on vugraph
- The confederate uses Amazon web services to crack all the rest of the boards for that session
- The confederate texts the hands to a players smart phone
- The player hits the head, whips out his smart phone, and ...
Research paper: "Security and Privacy Vulnerabilities of In-Car Wireless Networks: A Tire Pressure Monitoring System Case Study," by Ishtiaq Rouf, Rob Miller, Hossen Mustafa, Travis Taylor, Sangho Oh, Wenyuan Xu, Marco Gruteser, Wade Trapper, Ivan Seskar:
Abstract: Wireless networks are being integrated into the modern automobile. The security and privacy implications of such in-car networks, however, have are not well understood as their transmissions propagate beyond the confines of a car's body. To understand the risks associated with these wireless systems, this paper presents a privacy and security evaluation of wireless Tire Pressure Monitoring Systems using both laboratory experiments with isolated tire pressure sensor modules and experiments with a complete vehicle system. We show that eavesdropping is easily possible at a distance of roughly 40m from a passing vehicle. Further, reverse-engineering of the underlying protocols revealed static 32 bit identifiers and that messages can be easily triggered remotely, which raises privacy concerns as vehicles can be tracked through these identifiers. Further, current protocols do not employ authentication and vehicle implementations do not perform basic input validation, thereby allowing for remote spoofing of sensor messages. We validated this experimentally by triggering tire pressure warning messages in a moving vehicle from a customized software radio attack platform located in a nearby vehicle. Finally, the paper concludes with a set of recommendations for improving the privacy and security of tire pressure monitoring systems and other forthcoming in-car wireless sensor networks.
