Hack involves millions of Volkswagen, Ford and Chevrolet vehicles that rely on an outdated key fob technology. Researchers say keyless entry systems can be hacked using inexpensive technical devices. Volkswagen, reached by the Reuters news agency, did not dispute the claim and said its, current vehicle generation is not afflicted by the problems described The attack exploits two vulnerabilities; one allows an attacker to unlock nearly every model VW made since 1995, according to researchers. The other technique impacts key fobs used with Alfa Romeo, Citroen, Fiat, Ford, Mitsubishi, Nissan, and Peugeot vehicles.
