Senator Wants Automakers to Address Hacking

A U.S. senator has asked 20 of the world's biggest automakers for information on how they secure their vehicles from cyber attacks, in light of reports by security experts who say they have identified ways to hack into cars. Edward Markey, a Democrat from Massachusetts, asked the companies to respond to a series of questions including how they test electronic components and wireless networks to make sure that attackers cannot gain access to onboard networks.
