I don’t think that’s right when we know this is solvable. “My own car is fully susceptible to this attack. “This is throwing the gauntlet down and saying, ‘here’s proof this is a problem,’” says Kamkar. RollJam is intended to definitively demonstrate that lesson. With those precedents in traditional internet security, car makers should know that using rolling codes without an added code expiration measure no longer suffices to keep their products secure. In fact, Kamkar says his goal with RollJam is to demonstrate to car and garage door companies that they need to make that upgrade to expiring codes, or leave their customers vulnerable to interception attacks like the one he's demonstrated.Īfter all, Kamkar points out, two factor authentication systems like Google Authenticator or RSA’s SecurID use codes that expire in seconds, while millions of car owners still protect their vehicles with vulnerable systems whose codes never expire. Whats new in version 2.6.0.2: A Popup Killer Plugin an Internet Accelerator Plugin, a File/folder shredder, a drive space maker tool Added (Shred empty drive space), Cache Management and System. The latest version of Keeloq's chips, which the company calls Dual Keeloq, use a system of codes that expire over short time periods and foil his attack. With the new user interface and many new features you get an unbeatable collection of tools that make your Windows® system fast, easy and safe. Kamkar also says that Cadillac may be correct that its newest vehicles aren't subject to the attack. And while Whyte appears to have kept the code for his tool under wraps, Kamkar plans to release his on Github, timed to his DefCon talk Friday. But Kamkar says his refined RollJam is designed to better automate the attack Whyte used, without the need to attach the device to a laptop. Security researcher Spencer Whyte wrote in March of last year that he'd created a similar device. Kamkar isn't the first, as Cadillac implies, to invent the RollJam's method of jamming, interception and playback. Cadillac spokesperson David Caldwell wrote in an email that Kamkar's intrusion method "is well-known to our cyber security experts," and he believes it works only with prior model year vehicles, "as recent/current Cadillac models have moved to a new system." Liftmaster and Volkswagen declined to comment, and a Viper spokesperson said it's trying to learn more about Kamkar's findings. WIRED reached out one-by-one to each of those companies.
