NYU Tandon School of Engineering professor Justin Cappos talks about Iran's cyberwar capabilities following the death of Gen. Qassem Soleimani in a US strike and what we should do to protect ourselves. Cybersecurity expert Justin Cappos warns that Iran has already "proven it's both adept at launching cyberattacks and that those attacks can cause real damage" in the wake of the death of Gen. Qassem Soleimani in a U.S. drone strike. In an interview with Fox News, the NYU Tandon School of Engineering professor pointed to previous cyberattacks launched by Iran that he says illustrate the country has both the means and the willingness to go on the attack and damage American interests. In 2016, the Justice Department charged seven hackers linked to the Iranian government with executing large-scale coordinated cyberattacks on dozens of banks as well as a small dam outside New York City -- intrusions that law enforcement officials said reached into America's infrastructure, disrupted the nation's financial system and cost tens of millions of dollars. Professor Cappos said that because of the previous attacks and current turmoil, it is vital that people take measures to protect their systems.

Should you be worried about a car being hacked? USA TODAY's Jefferson Graham and Chris Woodyard break it down. Model cars run in a city miniature at the Elektrobit booth to show how software for highly automated driving works during CES 2018 in Las Vegas. Automakers and suppliers are making progress in protecting vehicles from cyber attacks, but the car-hacking threat is still real and could get increasingly serious in the future when driverless vehicles begin talking to each other. A worst-case scenario would be hackers infiltrating a vehicle through a minor device, such as an infotainment system, then wreaking havoc by taking control of the vehicle's door locks, brakes, engine or even semi-autonomous driving features.
