andy greenberg joins me now. why did you do the hack?, this was all actually the work of charlie charlie miller and chris valasek, the two researchers. they have been trying to do this for years to gain access to a wireless access remote vehicle. this is the first time they've done that and they named the automaker, detailed some of how they they did it and they'll talk about it at a conference, and show how it is done so researchers can test it out. all of it is meant to send a message to pressure the car industry to solve these problems, to take security vulnerability seriously. >> sreenivasan: how easy or difficult is it? should we be concerned there's 400,000 cars with this software inside it? >> everybody who has this one computer u connect in their dashboard needs to download the patch quietly released last week. gut it from their computer, put it on a usb drive and protect themselves. but it's a question whether someone could create a new hacking technique. it's possible but not easy. both are brilliant hackers. one a former n.s.a

joining me now is the reporter who took that wild ride andy greenberg, senior writer at "wired." anks for having me on. >> first, what was it like to drive a car that someone else was controlling andy? >> i think you could see in the clip that it was pretty terrifying. they blasted the vents and the ac was on high but i was still sweating. and i actually knew that they were going to do some sort of demonstration of their hack on me. i could only imagine if they didn't tell me what they were going to do. but i can only imagine how scary this would have been if you didn't have any forewarning, if hackers were really targeting you, you know, targeting unwitting victim from across the country. >> after the highway, you ended up in a parking lot where the hackers again took control of your car. let's watch. >> after that stunt on the highway, they still wanted to show me a couple other tricks. below a certain speed they can control the jeep's steering as long as it's in reverse. pop its locks, mess with the speedometer and, of course disable the brakes. hold on tight, hold on. >> he's

with an 18-wheeler behind him driver andy greenberg starts to panic. greenberg's a writer for wired.com. charlie miller is a security researcher for twitter. >> we wanted to show cars are vulnerable connected to the internet and that makes them as vulnerable as your phone or your laptop. >> they got through the entertainment system. they have control of everything from the engine to the entertainment system and even the brakes. sending the car into the ditch. on capitol hill, senators ed marky and richard bloomenthal bloomenthal, fiat chrysler says the hacking is a crime is issuing a patch to help. >> i told them about this in october, they had nine months to figure out the best way to fix it. >> reporter: you see all modern cars have the internet in them, don't they? it's very, very shocking. fcus says that this applies to vehicles with top stream on board. wired's demonstration took place in the jeep cherokee. but i think going forward this is something we're going to hear a lot more about i suspect. >> thank you john. the u.s. government is investig

driver andy greenberg starts to panic. >> it's dangerous. i need to move. >> reporter: a writer at "wired" and dpthe hackers trying to show it could be vulnerable. >> each one of those features is a hackable bug. >> reporter: they're able to control everything from the wipers to disabling the brakes. tonight, that recall including dodge, jeep and chrysler models. and now they're looking into whether other vehicles may be vulnerable, too. >> thank you. >>> coming up the war between neighbors. this man using a bulldozer to tear up a fence that doesn't belong to him. one of them in jail tonight but is it fair? >>> and the answer to the mystery on the beach. >>> and a stranded orca, crying for help. and the people on the beach that came to its rescue. we'll see how this ends. introducing otezla apremilast. otezla is not an injection or a cream. it's a pill that treats plaque psoriasis differently. some people who took otezla saw 75% clearer skin after 4 months. and otezla's prescribing information has no requirement for routine lab monitoring. d

highway drive -- >> i can't see anything because -- >> reporter: -- quickly turned terrifying for andy greenberg>> hold on tight. hold on. >> reporter: as hackers remotely took control of his 2014 jeep cherokee, sending him into a ditch. greenberg, a reporter for "wired" magazine, did this on purpose working with cyber security experts, hackers, to show how some connected cars can be vulnerable. >> it ceased to be fun. so i can only imagine if the same thing was done to you without any forewarning whatsoever, how much fear that could instill in someone. >> reporter: the hackers in the "wired" article accessed the jeep through its infotainment system to change the radio and the ac and in a much more dangerous move to kill the engine. >> you've got to turn the car off. >> reporter: the two researchers believe that as many as 471,000 vehicles are potentially vulnerable. they've only verified that on a 2014 jeep cherokee. >> reporter: chrysler, which owns jeep, released a software update this month and says it has a team focused on identifying and implementing software best practices including cyber

driver andy greenberg starts to panic. >> it's dangerous. i need to move. >> reporter: a writer at "wired" and the hackers trying to show how some new cars with internet connections can be vulnerable. >> navigation, entertainment. each one of those features is a potentially hackable bug. >> reporter: they're able to control everything from the wipers to disabling the brakes. >> hold on tight. >> reporter: tonight, that recall including dodge, jeep, and chrysler models. and now regulators are looking into whether other vehicles may be vulnerable, too. linzie janis, abc news, new york. >> thank you. >>> still much more ahead tonight. we want your opinion. the war between neighbors. watch this. video showing this man using a bulldozer to tear up a fence that doesn't belong to him. one of them behind bars tonight, but is it fair? >>> and, the mystery explosion on the beach. the woman thrown into the air. investigators revealing the answer tonight. >>> and a stranded orca, crying for help. and the people on the beach that came to its rescue. we'l

. >> with an 18-wheeler behind him driver andy greenberg starts to panic. >> seriously. need to move. >> greenberg is a writer for wired.com. charlie miller is a security researcher for twitter. >> awe wanted to show that cars are vulnerable and they're connected to the internet. that makes them as vulnerable as your phone and laptop. >> they had the potential to take over control of everything from the radio to the wipers and even as miller found out, the brakes. sending the cherokee uncontrollably into a ditch. days after wired story appeared online chrysler said they were announceed the recall. charlie miller said that he has little sympathy. >> i told crisis letter back in october. they've had close to nine months to think about it and figure out the best way to fix it. >> okay, you can uncover your eyes now. it's safe to look at the screen once again. afcus says the recall applyies to vehicles with eight-inch top screens. you have one of those. dodge vipers, durangos, chargers and challengers. it took place in a jeep cherokee not a grand cherokee. >> how scary is th

. >> >>joining me on set is andy greenberg, who you just saw in the video.ighway, they told me they would hack it. it started out with trivial things, the radio and wipers soon after that they disabled the transmission. >> that's scary even in an experiment. you're doing it for the first time. let me ask you, a lot of people may find this surprising. explain to us how they are able to actually get into the functions of the car in so many different levels. we saw on that video, even the car's lock system was activated remotely. >> many cars today are essentially a smartphone. these two researchers found that 471,000 chrysler vehicles with a certain computer called u-connect, that computer's internet connection was vulnerable. they could hack into the computer, take it over reprogram an adjacent chip in the dashboard and send messages to all the physical components of the car, like brakes steering and transmission. >> those systems are integrated not separate? >> they are supposed to be separate. that's part of the vulnerability. this is about telling chrysler

. >> wired magazine reporter andy greenberg volunteered for this.rdinating with hackers to show how tech connected cars can be vulnerable. >> cease to be fun. i can only imagine if the same thing was done to you without forewarning whatsoever how much fear that could instill in someone. >> reporter: the hackers accessed the jeep to its infotainment system and managed to take full control even killing the engine. >> the two researchers believe that as many as 471,000 vehicles are potentially vulnerable. they've only verified that on 2014 jeep cherokee. >> reporter: chrysler which owns jeep, released a software update this month and says it has a team focused on identifying and implementing software best practices, including cybersecurity for all vehicle content, including on-board and remote services. >> this is the good and bad. it took the demo on a highway for them to all of a sudden get serious. >> reporter: cybersecurity expert says the growing risk of hacking the so-called internet of things should drive change in silicon valley, not just in au

. >> what started as an ordinary highway drive quickly turned terrifying for andy greenberg as hackersl of the 2014 jeep sending him to a ditch. they did this on purpose working with hackers to show how some connected cars can be vulnerable. >> it ceased to be fun. i can only imagine if the same thing was done to you without any forward earning how much fear that koul instillcould instill in someone. >> they hacked it to change the radio and pc and to kill the engine. >> you have to turn the car off. >> the two researchers believe as many as 274,000 vehicles are vulnerable. they only verified that on a 2014 jeep cherokee. >> chrysler released a software update this month and says it has a team focused on identifying and implementing software best practices including cyber security for all vehicle content including on board and remote services. a bill would require that connected cars protect drivers against cyber criminals and have technology that can stop a hack in real time. it does introduce more ways to get into the vehicle but they're working together to beef up security. >> stayi

>> that is andy greeneberg behind the wheel and writes for "wired" magazine and willingly put him in hands of hackers. hackers can gain control of some vehicles via the internet so greenberghis jeep cherokee and they took control from everything to the radio, windshield wipers. let me bring in one of those hackers with security research io active. nice to talk to you. >> pleasure. nice to talk to you. >> said hacker in this case. you know let's walk through this because when you -- when i hear about, you know radio or windshield wipers dare i ask how tough this was for you? >> this was an accumulation of almost three years of research, and the jeep alone took a year for dr. charlie miller and myself to investigate, examine and then remotely compromise the vehicle so this isn't something you do over a weekend or at night when you're bored. >> okay. so you did your homework but bottom line you did pull it off and what you did from my layman's understanding is you essentially hacked into the internet into the car which allowed you to go deeper into the radio and windshield wipers et cetera and there's cars on the road equipped with this technology that would increase the vul
