Earlier this year, a Fiat Chrysler recall drew attention for the way it handled hacking vulnerabilities in some of its vehicles. But what systems are really the most at risk in these situations?

To recap, the case was reported back in July, when the manufacturer attempted to fix their vehicles by mailing USB drives with software updates on them to owners. The company also put the update on its website. The security issue caused concern because it showed how hackers could theoretically control a vehicle remotely.

RCR Wireless News recently quoted security solutions lead Martin Hunt explained some of the systems at risk, which include tire pressure management, WiFi connectivity and keyless entry. Situations like this may show a possible future model for businesses to follow, using the distribution of drives as a model for how they inform owners.

Thank you for watching.
