An anonymous reader writes from a Wired article: A group of German vehicle security researchers has released new findings about the extent of a wireless key hack, and their work ought to convince hundreds of thousands of drivers to keep their car keys next to their Pudding Pops. The Munich-based automobile club ADAC recently made public a study it had performed on dozens of cars to test a radio 'amplification attack' that silently extends the range of unwitting drivers' wireless key fobs to open cars and even start their ignitions (in German). The ADAC researchers say that 24 different vehicles from 19 different manufacturers were all vulnerable, allowing them to not only reliably unlock the target vehicles but also immediately drive them away. "This clear vulnerability in [wireless] keys facilitates the work of thieves immensely," reads the post. "The radio connection between keys and car can easily be extended over several hundred meters, regardless of whether the original key is, for example, at home or in the pocket of the owner." [...] Here's the full list of vulnerable vehicles from their findings, which focused on European models: the Audi A3, A4 and A6, BMW's 730d, Citroen's DS4 CrossBack, Ford's Galaxy and Eco-Sport, Honda's HR-V, Hyundai's Santa Fe CRDi, KIA's Optima, Lexus's RX 450h, Mazda's CX-5, MINI's Clubman, Mitsubishi's Outlander, Nissan's Qashqai and Leaf, Opel's Ampera, Range Rover's Evoque, Renault's Traffic, Ssangyong's Tivoli XDi, Subaru's Levorg, Toyota's RAV4, and Volkswagen's Golf GTD and Touran 5T.
