Slashdot Mirror

schwit1 writes to point out an experiment undertaken on the campus of the Netherlands' University of Twente, in which two wireless sensing stations were able to cheaply pinpoint a target vehicle equipped with "smart" V2X systems nearly half the time, and track it (albeit less precisely) even more, according to Jonathan Petit, Principal Scientist at software security company Security Innovation. "You can build a real-time tracking system using off-the-shelf devices with minimum sophistication," says Petit. In a paper to be presented at the Black Hat Europe security conference in November, he describes being able to place a security vehicle within either the residential or the business zones of the campus with 78 percent accuracy, and even locate it on individual roads 40 percent of the time. The tracking here was accomplished by listening for transmissions emitted over using 802.11p at 5.9 GHz. Says the article: Petit is now working with Ford, GM, and other carmakers to develop strategies to help secure connected cars. One interesting finding from his experiment was that a Manhattan-style grid of roads makes it difficult for potential attackers because there are more connections between the intersections. "This raises the idea of privacy-enhancing road networks, where cities are designed with the concept of privacy at their core," he says.

Herbert H. Thompson, PhD ("Hugh" to his friends), is one of the people featured in the HBO documentary, Hacking Democracy, that Diebold tried to keep from airing. Hugh is a long-time Slashdot reader who called me to volunteer for this interview — on his own, not through anyone's PR department. Here's a YouTube excerpt from a CNN Lou Dobbs show with Hugh in it. (Find more articles by and about Hugh here. And perhaps check this brand-new MSNBC story about e-voting, too.) Hugh suggests that you give him "your wildest questions about what went on behind the scenes and how safe the e-voting systems actually are." Let's take him up on that challenge, hopefully while following Slashdot interview rules. Note to Diebold and other voting machine companies: We welcome comments and questions from you, same as we welcome them from everyone else. If you feel you are being vilified unfairly by Slashdot readers, please respond and set the record straight.

Last week on Slashdot you saw a (Microsoft-funded) research study on Windows vs. (Novell) Linux reliability by Dr.Herbert Thompson. Novell disagreed with the study's conclusions. So did most Slashdot readers. Thompson's work been mentioned on Slashdot before, especially his famous five-line script that could change electronic voting machine results and his novel, The Mezonic Agenda: Hacking the Presidency. He's a real, genuine-article computer security expert (and regular Slashdot reader) who is happy to put on his flame-resistant suit and discuss his Microsoft vs. Linux study with you. So ask whatever you like, one question per post. We'll send him 10 of the highest-moderated questions and publish his answers next Monday. He'll jump into the discussion then, which ought to make it rather lively.
