![]() ![]() To determine just why those errors occurred will require the user to have honed reverse engineering skills, understanding just how the CAN operates and what functions relate to what data packets. Once errors show up, however, the average person's attempts to find weaknesses in their car's network will likely founder. Just feeding a log file from the car will create the emulated version, allowing testing away from the vehicle. ![]() "Once it’s learned the car, it can learn to be the car," Smith told FORBES. There's then no need to use a physical car to test for vulnerabilities. The Snap-on Cloud Global OBD-II Software Upgrades & Service Releases. It also does more than fuzzing the software maps out the car network, known as the CAN, automatically identifying modules the user can interact with. Unlike its predecessor, which was usable only in command line, UDSim is controlled via a simple graphical interface. Though he thinks the easiest way into a dealership's network would be through the often-shoddy Wi-Fi. Smith believes that a "Trojan car" containing malware could pass on infections to those tools, which could in turn jump on to other cars. Combined with fuzzing software, it sought to expose flaws in diagnostic tools. The older system used hardware called ODB Gateway (ODB GW), a tribute to Ol' Dirty Bastard, the late WuTang rapper, and a common mispronunciation of OBD (on-board diagnostics). UDSim is an expanded, user-friendly version of a tool Smith released last year, which sought to expose a potential weakness in vehicles: the use of OBD2 diagnostic tools to spread malware. ![]()
