Renowned hackers Charlie Miller and Chris Valasek warned on 21-Jul-2015 of a ridiculous vulnerability in the computer systems built into Fiat Chrysler cars: the flaw can be exploited by an attacker to wirelessly take control of the engine, brakes and entertainment system.
The cars connect to the internet via Fiat Chrysler’s uConnect cellular network, and thus can be accessed and tampered with from miles away by anyone who knows the vehicle’s public IP address. No authentication is required.
