DEF CON 23 - Robinson and Mitchell - Knocking my neighbors kids cruddy d...

##########################################
Everyone thanks very much for .
Coming god this talk was fun to make and I'm glad it follows up the last one.
Um I have a few some of the stuff that I present is a little different than the stuff that they talked about.
So just to get a few things out of the way a couple of shout outs to some guys who helped me some of them could be here some of them couldn't.
There's a few folks who wanted to be nameless so their names are printed in black.
So we're gonna kick it off my neighbor and his kids are just annoying.
Snots right insert your own four letter word and God and the problem is way too much discretionary spending because then all of a sudden one day this thing showed up and the kid is following it around all over the neighborhood and you can tell because he's crashing into every car every house every tree and he's running down the street with it and at night.
It's really obvious what he's doing.
Because it just shows up and it's like really dude that's what the internet is for and my initial response from all that stuff is.
Hmm maybe take that you little bastard.
But if you are here in the last presentation they say shooting down drones is a problem and that's okay i don't want someone shooting down mine but this got me to thinking what if the following things were to show up such as maybe this not hard to do.
It's actually made the news some guys up in New England started mounting semiotic semi-automatic pistols to their homemade drone that interesting.
What if this showed up I can see the first shot being fairly accurate after that a no one's business.
What would happen if this showed up yet not as cool so I started looking around online and it turns out that there are building a bazillion regulations and everyone is trying to regulate unmanned aircraft systems you is right which we call drones or quadcopters and it turns out most of the regulations that are out there are not to restrict hobbyists most of them are there to restrict the government's use of quadcopters and drones and there's a lot of attacking going on on the commercial space where you have to get certain FAA approval to fly and it turns out i was flying my DJI phantom 3 while testing for this presentation over a parking lot and I was watching it and a guy came up right behind me and he goes hi I'm actually from DHS is enforcement division for drones in the DC area and I like fun yeah he goes to know what the rules are yeah he goes are you doing this for commercial use and I said no he goes okay see ya.
And I followed him and I wouldn't want to be on like a I got questions if he goes dude I have so many problems about guys find those things around and I said what was your last problem he said a guy flew his quad copter over national stadium and lost it.
And I said well how did you ever find the guy and he said easy most of the guys who lose these things you see them running over the hill with their controller have you seen my drawn right and I'm like really he goes yeah at which point we were waiting for him and we scooped him up but it turns out that non-commercial use hobbyist use of drones is largely not regulated.
There are a few things that are out there right there are no fly zones around Washington DC and it centers around the White House and goes out 15 miles there's actually supposed to be a no-fly zone of five miles around the airport unless you get permission.
Apparently the ceiling is supposed to be graduated at you get closer.
The ceiling goes down but FAA tries in some of the literature just say five miles that's it it turns out you're not allowed to fly on military bases that's considered bad.
This came up in the last presentation you are not allowed to launch or land from a national park.
However you are allowed the flight in their airspace it is not theirs to regulate however they can cite you for reckless endangerment if it potentially could crash on someone and they get people on that and they confiscate the drone there.
There was a guy out over the Grand Canyon filming some sunset people complained.
You know this guy in Smokey the Bear hat showed up and and took the guy away with his drone there are temporary flight restrictions that are issued for disaster areas wildfires stadiums large assemblies and whenever there's going to be a presidential visit and they do it several hours before and during the visit.
You're not allowed to mount a gun on you is because technically becomes a weapon system there is a 400-foot ceiling.
Amazon is now petitioning to try to get several hundred feet for themselves to deliver packages and then they want to a ban of a hundred feet from everyone you also have to fly within line-of-sight and I have it now counted up to 16 states have now enacted their own laws and technically according to the guys I spoke to a DHS to do enforcement a lot of that airspace is.
Not theirs to restrict now the five mile area around airports essentially knocks out almost all of new york city with the exception of a few parks you're not allowed to fly above the sidewalks in New York City because of the reckless endangerment and safety issue and then people getting out there in the hobbyist area um there's a whole bunch of restrictions that come up right if you don't do it for commercial use your under 55 pounds right your not interfering with any manned aircraft you can be good to go but that's nice and all but most people don't know the rules because everyone in a brother is trying to create them this is a listing of all the no-fly zones on the eastern side of the US and and that's a lot of them if you log into parents website.
This is a listing of all of the recordings that got.
Automatically updated to their website that shows everyone who was flying on the eastern side of the US isn't that interesting over 2,000 flights in DC which is technically a no-fly area and over 2,000 flights in New York City.
Um if you do a quick overlay of the maps.
Yeah turns out people are flying in areas that they don't know about and if they're smart you know I say it's interesting and and that's nice and all that the rules are all there but my neighbor's kid is still annoying and I know he doesn't read write and he's not getting the appropriate parental guidance so it brought me up with the bigger question is there any way to take that thing down the grateful or ungrateful I thought there might be a couple of ways there's a couple i can think of a few ways but maybe something a little more subtle would suit our needs so maybe the next time he's there he doesn't capture video maybe it knocks it down and flies away and if you've ever seen this guy crash.
He actually bounces like that so let's take a quick look I'm going to take a look at two different drones two of the more popular ones on the market one is going to be the parrot bebop drone which has a 1080p lens on the front the other one is going to be looking at the new DJI phantom 3 and if we start by looking at the parrot Ron we had get up roughly a rough listing of the specs and it turns out sure we got a quad core we got memory.
We got a top horizontal speed of 45 miles an hour.
Wow right linux but if you look really carefully at the specs hmm.
Yeah.
The thing is its own flying router with dhcp enabled awesome.
There's something else I found really interesting if you read the specs.
It's got a really interesting GPS chips in there using American gps and Russian base gps so what happens if i muck with that right there is a couple other things that kick in the free definitely easy for me to say the free flight three app is installed on your android device for your iOS device you can get updates to that if an update comes out.
You don't have to forcibly install that update you can ignore it it doesn't come through the app store it actually is just sitting there are checks their website so you can apply the update a couple other things that are interesting.
The return to home function and I'm sitting here thinking all right if he's flying near me and I want to swat it and get it away.
Maybe I can take advantage of the return home function and send that thing back home the height distance thing is very interesting if the thing is flying above 10 meters it will fly back to its original return to home . if it's flying less than 10 meters the thing will automatically shoot up 30 feet turn face home and then fly home in a straight line so if you have a house where you can pick up GPS and say you're in your living room with a ceiling fan.
You may not want to hit the return home feature because that gets very ugly fast.
That's how I lost my first drum there's something else I wanted to take a look at and I see this in your documentation if the bebop drone loses connectivity with the controller for 30 seconds.
This thing is supposed to fly home hmm hmm.
That makes me want to say what would happen if I screw with that the Wi-Fi signal or what happens if I screw with gps or what happens if i introduce a magnetic field around the thing so let's go through it real quick this thing actually flies with its own mac address it's running dhcp we can actually scan this with a number of tools I happen to have a pineapple robber around I didn't use Darrin kitchens infusion which is really cool actually didn't know that infusion existed at the time but it's neat there's an underlying Wi-Fi connection that gets established between the two devices and then on top of that the applications talk to one another.
So let's introduce ourselves a little mischief shall we what happens if we do off our original connection for say 30 it turns out the return the home function did not work correctly for me and I did this like five times.
I lost like six propellers at the time doing this test here's what it looks like when all of a sudden this thing gets d off for 30 seconds it sits there and flies . it just landed all of the rotors stop at the same time it went straight down maybe it got lost maybe thought that was going to be home I don't know but clearly that didn't work so now i can just walk out onto my property and pick the damn thing up you want it come & get it maybe there's something else we can do I got it.
Let's give it a quick stem and it turns out when we scanned within that.
Yup it's a flying ftp server just floating around.
That's awesome i had 10 devices simultaneously connected to this guy.
All at once only one app was talking but the other nine were sitting there waiting we'll get back to that in a second it turns out this thing is a flying ftp server and there are two particular directories i found interesting one was the media directory with a little monster next door was filming videos and the other was a thumbnail directory.
No authentication was required to connect over ftp I think that's fantastic.
So I was sitting there and thinking while it was in flight maybe I can grab his pictures and replace them with something like back.
That was a fun day.
Yet well that was cool alright so i'm doing i'm taking the videos you got of all the neighbors because maybe i want to just see what they look like but then there's this monstrosity telnet wide open while the thing is flying which kills me so I tell not directly into the box and here's a listing of the entire directory structure right there now it's running it's running busy box from like three years ago.
Write this thing i purchased just a couple months ago for this presentation and they never updated busybox there have been something like ten updates too busy box since this came out but they haven't updated it but i want you to look really carefully at three things for me take a look at those shell script sitting right there so I took drone number to this gets to be a very expensive research project soon he was hovering in my kitchen.
I tell that directly to the box and all of a sudden I see that I'm like that's pretty cool so I wonder what happens if i type in this.
And hit enter I am suddenly greeted with all of that I was sitting there working in the kitchen.
It was hovering and then all of a sudden it took out my stove I was thinking the shutdown feature would gracefully just shut down the rotors and down it would go this thing.
There was no graceful shutdown it literally flew right by and I'm like wow.
So if I was one of those cool dudes who got like carbon fiber blades.
This is what it looks like in the park.
It's flying hit the command their flank and down it goes there is no restart from that right if you go look at some of the software exploits are out there.
It kills a running process and the thing fires back up this is off.
It's done by the way in case you missed it because it always looks better in slow motion punk if it's running near a wall it gets up draft and there's no telling where it's gonna go I was going to do that in here today.
I fired this up this morning and six wonderful conference attendees had connected to my open till net connection I'm not bitter but you did steal my thunder.
So there's another thought I mean shutting that thing down great so I had a co-worker overlook this is and said you know that's not really epic you should watch that thing like 400 feet in the air traffic and I'm like will give me your drone so why don't we just take the damn thing right.
Kid you're not your ball into my yard I'm going to take it so we actually have two simultaneous connections to the same drone at the same time if I am sitting there and I again remember i had like 10 devices all connected to it.
Simultaneously.
This is what it looks like from the ipad that is currently controlling the bebop drone it has access it's hovering at one meter.
I ran this inside a hotel lobby they were not happy.
This is what my iphone sees ok I'm connected to the network but my apps not connecting this is what we have hey wait a second why don't they just send a quick d off the moment that day off kicks in the controller automatically says I'm disconnecting right away he is automatically having a bad day so the question I have for you is in this race condition who's going to win if he is running an ipad anywhere near indoors he is going to pick up his home network or any other network before he picks up his bebop drone connector which i think is great.
Which means he is going to sit there and try to reconnect even though his underlying network connection is not there and it's going to freeze meanwhile on my iPhone I've connected on there and I was sitting there and I connected because I do often my Wi-Fi connection was good no the altitude listo on this it now thinks that is 0.
The thing was three feet in the air so it didn't get an update for that which means i'm often running and now i am the guy who is in charge of that drone and he can't do anything about it if I click the button at the top that says emergency that thing just falls from the sky in a way it goes.
Which i think is great one of the other things that kicks in with the free flight app that runs on top of the network connection again it.
It's gonna pair to any other network before it comes back to this particular drone and I think that's fantastic now for those little enthusiasts to have more money the bebop drone comes with an optional sky controller that looks like this it's supposed to be a range extender.
It turns out that that is its own wireless access point to and it's wide open.
Which means we can do off in one of two spots if we do off between the ipad which is literally just sitting in the cradle it is not tethered it's just sitting there connecting wirelessly if ID off that and i connect my iphone or my iPad to it all of a sudden I get these little controller icons sitting right there which means i have control of you if I'm nice i will temporarily send control back to your controller and then I'll steal it away from you and I can go back and forth which means he's going to respond all over the place which means his mind I don't have to worry about it I mean I think coding would be great writing an exploit would be great but the app is free it's hardly been developed until that's wide open so what happens if we start looking around at other areas like GPS right and this is interesting because if you pull up the specs there are several very specific frequency ranges used in the US and very several specific ranges used with the Russian gps system what if we screw with those signals.
Now there's one teeny tiny little problem that it's illegal like 18 different ways of illegal like you're currently find sixteen thousand dollars for every day that you do this up to a hundred and twelve thousand dollars and if you go to the FCC's website they have a spot where you can report people they list of all the people that they sent notices to and find so what to do.
I talked to the DHS guy i said hey I was thinking about doing research and his flat answer was are you going to cite my name and I said of course not he goes they would never catch you if you do it just wants me they can't.
Ok so I spoke to an attorney an attorney said yeah it's it's still illegal no matter what they could still come get you in like you're no fun.
I was speaking to a cop and he said you know if you go back and read the specific intention that shows up on the FCC's white on the FCC site they don't want you to put anyone in danger right you can't disrupt anyone else a signal if you showed up here 20 miles away from everything in the woods and you're being supervised hypothetically you could test and no one would know i'd like to introduce you to my new friend.
Selling and manufacturing and importing and all that good stuff related to gps jammers is illegal this is a GPS test generator and hypothetically one could pick this up one line for a very reasonable price of twenty-five dollars.
He is specifically designed to block these particular frequency ranges.
He also has an effective range of about 20 meters which is kind of creepy.
So I go out hypothetically with some people to do a test and I'm sitting there observing we do the test at which point the police officer says I'm going to take your equipment now I'm like really.
He is yes I there's no way I can let you walk away with that and it's gone so it's been confiscated in history but if we were to run that type of generator on the bebop drone while he was flying the return to home feature automatically sales instantly from the point of view of the drone it is currently flying it has gps and then all of a sudden everything stops.
He automatically goes to hover mode it doesn't move forward he doesn't move back he just freezes and if he gets GPS signal again.
He doesn't resume his take on function he just stands there well I lost and he is just looking around.
Which i think is a very interesting thing now it doesn't overwrite what the home position is it just interrupt the flight home.
The same thing could be achieved if you flew under a bridge or fewer underneath some dense trees all of a sudden this thing just stops in place which can be a problem.
Introducing a magnetic field around the device say magnets from hard drives actually had no observable effect on the guy which was a little disappointing for me.
Now if you're thinking about taking over someone's thrown say the hotel at six o'clock the morning you bastard.
There's going to be references on your devices that you've made connections to the device very specifically you want to take a look at the free flight three plist file from your iOS devices and delete that because that will have date stamps timestamps and the serial numbers of my drone in your phone so you might want to smudge them out if you can.
And i think that works so this thing I would never fly it around any of you ever what if we took a look at something bigger though something bigger than the bebop drama.
Yeah okay not bad maybe if we took a look at the Phantom 3 that just came out this past June.
What do we do there if we look very specifically at these specs this thing is designed to have certain geofencing in place because of the incidents that occurred earlier this year um it can fly up to several hundred meters away without an issue.
The top horizontal speed is about 35 miles an hour on that it uses both gps systems as well in some geo fenced areas it will give you a notice that says warning you're in a bad spot in the other ones it's supposed to automatically take it down where it uses an automatic landing sequence.
This thing is very freaky with respect to magnetic fields though it requires constant calibration if you're going to take off anywhere near magnetic field and I find that mmm electromagnetic field interference I think that's pretty cool.
DJI phantom 3 updates I've heard this from other presenters and I respectfully disagree.
Whenever an update comes out by DJ I for my phantom 3 I get a warning message right before i take off and says sorry dude.
You cannot take off until you apply that update and I'm like it's like uh huh I contacted their tech support on three different occasions to get three different guides and I said hey what's the deal with your updates and are like sorry man that's the way it is.
We have an update you have to apply it to your device there's no way around it and I'm like what if i want to roll back there like uh huh.
I'm like what if it fails part way through it like they're like dude you're screwed.
I'm like that's your answer he goes pretty much.
Insert the microSD card try again so let's kick it off what happens if we disrupt the Wi-Fi signal going to a fan of three well it turns out it doesn't do anything because the Phantom 3 doesn't operate over Wi-Fi which is kind of cool but it brings up the other question of what happens if we start to disrupt the GPS signal now if you look very carefully at the gps app.
I'm not talking about what's installed on the device itself i'm talking about the app itself it turns out there's a little teeny tiny database called fly safe places and it's very interesting as of july twenty four that database had 10,000 914 entries.
It contained the latitude and longitude of all of the no fly places that were listed in it contained the country ID the city the name of the location what type of shape was around it what the radius was whether or not it was going to issue a warning to the user whether or not it was going to issue you know it disabled and then there was a time stamp is too when it was added to their data base I very easily downloaded this database and started just changing entries which I found to be very interesting so when did DJI phantom 3 is flying you get something that looks like this in a very nondescript area at the very top it shows a safe to fly gps indicator.
No problem there's a map in the lower right corner.
Hypothetically if someone were to turn on a GPS test signal generator all of a sudden everything goes to this it automatically loses gps if I am flying the device and I start to look at its own diagnostics it comes back and tells me what frequencies it is using to send video signal back video signals back to my ipad when gps is disrupted all of a sudden things start getting squirrely it turns out my video started to become choppy.
It had a lot of latency it also turns out when they returned the home feature was working it lost gps the thing was flying home could be right here and here it comes and here it go.
Hey there it goes it missed its home . completely flew by if you've flown a DJI phantom 3 is in here flown of a DJI phantom 3 aren't they awesome lots of finesse to it right not a whole lot to it all over the finesse to my phantom 3 was completely gone.
It's like I was flying this thing all over again so I'm sitting very controlling it I was taking it turns out it almost hit someone they got a little upset.
So in slightly windy conditions or if you're near a building hypothetically there's a downdraft and then all of a sudden he becomes unstable and he crashes so it's a combination of the windy conditions and where it's flying along with losing jps if it started with GPS which i think is a very interesting thing.
There's something else i also noticed what happens if we play around with the magnetic field around our DJI phantom 3 it turns out whenever it launches if it can't get a good magnetic compass reading it's going to say hey dude I can't fly until I get calibrated so you pick it up you turn it on all three axes.
It says I'm calibrated you set it back down if it loses that magnetic field.
Guess what happens sorry dude I got to recalibrate again and you're like really I just calibrating you.
You pick it up you twisted your roll it you're good to go so if you were to fly and say take a couple hard drives from say some of your old hard drives hypothetically you left them in the area.
This thing is not taking off it'll never get off the ground which I found to be really interesting it is very sensitive in that area a lot of things going on.
D off on the bebop drones and any of the parrot series very quickly disassociates the controller with the device yeah you got it out online digital gps interference definitely screwed up the return to home function.
It causes a device to stop and the other one it misses its home sequence if you take a look at the magnetic field you can't launch with the DJI phantom 3 has a lot of performance issues and then lastly sure there's physical objects with you can always throw it to things instead of shooting it down just to kind of mess with our people there are tons of references in this space on looking up what people are doing what regulations are there they are constantly changing people are passing laws regulations and all sorts of jurisdictions based just on personal opinion well I just don't want them in my space because it all and when my quiet time at the beach okay well you're screaming kid annoys me at the beach all right i'm not defending him and sending him away.
Leave my daughter alone right but there's all sorts of rules you can also go through and take a look to see which type of frequencies are allowed in different regions in which ones aren't.
So it's going to vary from country to country it was a fun research project.
I knocked my neighbors cable and his drum offline.
Thanks.
I'm almost afraid to do this do you have any questions yes sir you in the front yes even any questions for I'm gonna go see my friend over there I'll be right back take it.
I'm so you mentioned interfering with the GPS signal.
How about modifying or sending a GPS signal with different coordinates you theoretically you can do that since gps l1 is not encrypted you could send the signal provided your signal is stronger than that of say the official signal.
You could very easily television it somewhere else without any problem.
I mean no problem easy to do that all right if you have questions come up here in queue up so i don't have to walk my fat ass around the room cool thanks very much all right I'm i think seems in New Jersey right your-your-your is a Maryland here where you teach is that in New Jersey and Maryland or Maryland ok I'm sorry I could in the photos and injuries but anyway the New York University Nazi institute all ok there you go.
Anyway in the New York area past couple of weeks there's been a couple of drones buzzing commercial aircrafts are coming in and that it's like for 4,000 feet.
What happened to the you know the geofencing in the forefoot ceiling and everything right so when the DJI phantom 3 you can actually turn off that ceiling limit and it will prompt the pilot to say hey dude the FAA says 400 feet and you can be like yeah whatever the thing can go up to about 1,500 meters there is a video of the guidance sweden who decided it would be a great idea to take his phantom drone fly it up 1,000 meters above the clouds to sit there to get some views and then all of a sudden.
Oh crap I lost control of it I can't bring it down it'll come down eventually and it crashed 500 meters away and he said I was safe she got ridiculed online he's like well I'm i was good there like now dude you're an idiot.
So you can turn off that feature you can also go into a mode autonomous mode and just fly is that possible deactivated technically right so he wants to know is it possible why is that even possible and the idea is you can very easily turn that theoretically you could get permission from fa in the air traffic control tower to fly in an area provided you register with them for commercial reasons so you could have a reason to fly that high so you could turn it off.
It's up to the flyer to take control at least right now got the grant you probably not how's it going Michael in your research you mentioned that that the Phantom 3 controller was not using Wi-Fi.
Were you ever able to figure out how that controller worked but i was looking and I know it's doing communication over some RC channels traditional RC channels and I just haven't had time to go intercept that traffic I feel like a light bridge on the got it something other than the 2.4 2.5 gigahertz range so typical RC controllers I couldn't get that the video comes back have you played out the 3dr solo at all.
I have not played around with that yet ok yet.
So you mentioned that you were able to pull down the database and look around inside it for the no-fly zones.
Did you experimental with making your house a no-fly zone technically there are certain websites where you can register your property as a no fly zone i added a database entry real quick.
But I hadn't had a chance to finish everything I took out several entries.
I went back and forth so is there any authorization required to connect to that and downloaded or were you able to openly connect to that and downloaded like would you be able to do that to your kids to GI phantom 3 get the DJI phantom 3 app and the bebop parrot's our own app are all free for anyone to download so you can download it specifically to your iOS device and and pop out the database and start messing with it looking around but what I'm thinking is your neighbors drone can you connect to that download the data base i will own house and then send it back to his drone so he doesn't know why but all of a sudden he can fly around your back here I like your thinking but the database is stored on his controller not on the drone itself.
Yeah so question about the I guess the the database in the gps in relation to the regulatory structure for drones so my understanding is that the FA has a regulation around no-fly zones.
That's predicated on the database in the gps being accurate.
So is there anything that you know of either that the FAA is doing to require stronger authentication.
Or inhibit gps jamming you never know i'm not familiar with what the fááá is trying to do in plant in other ways.
I'm and the follow-up is so if I go in a nice pool gps . turn it off or if I spook the database would i be able to technically fly the device in a no-fly zone well technically right now if you want in the bebop drum I could fly anywhere.
The Phantom 3 drone i can put it in autonomous mode instead of P mode p mode uses gps a mode doesn't technically I could fly that anywhere which is kinda crazy right.
And people are doing TGI drones wouldn't have any of that stuff and they can fly their stuff anywhere so crazy stuff one common question arm I fly model planes they also may hang glider pilot so very familiar with the FAA and what they like what they don't like so 1 comment would be number one it needs an organization privately for somebody to say hey listen we don't like the regulations that you're running so there's the United States hang glider a paraglider association of course the ma is an association for <time> six </time> modelers so I think that's one area we need to go in and if we don't like what everybody else is going to come up and write for us.
Number two I love the way that one that was on there that was when I was curious about this was able to tell that into a while that other person was still in control the yes does that so my next step was well why don't you just like going to the little kids app could you the idea that you happens on his device right but where you're able to then Traverse back down to him possibly i didn't bother I just stayed on on the device itself and I just knocked down so while someone was flying that bebop drone someone else.
I tell me that it directly into that bebop drone while it was running I had three other devices acquire dhcp addresses and then with the telnet connection I just issued the shutdown script and.
Calm down you want how about our - our I could it.
Theoretically I can play in there all day you said that you are able to disrupt the flight by jamming the GPS signal or well Jamie would be illegal about messing with the GPS signal that were you able to regain control of it just by switching it to attitude mode and that once in on the bebop drone.
Once a GPS signal that was being interfered with went away she we eventually reclaimed his own gps and then the return home feature worked again.
Ok on the other one the moment that signal was disrupted when it reclaimed gps and it was much faster than it was fine and then away goes and finesse came back the interesting thing on the fan 3 is if you also take a two inch by two inch square of aluminum foil and put it directly over the top of the DJI phantom 3 completely interferes with all of the GPS signal reception all of it just like that thanks sure.
Thanks Patrick Tucker with defense one so I sum up thanks to program presentation a few of the issues that you mentioned aren't entirely new many of them are it did you approach to either manufacture with any of these things that you found and follow-up to that if you were to make a recommendation to policymakers RFA people about how to deal with some of these.
Vulnerabilities.
But with that recommendation be my recommendation quickly back to parrot would be dude would you please shut down the services while the same thing is in flight.
Please at least for mine right the other ones i mean it would be nice if there was some database that was reliable and I couldn't get to and muck with and that sort of thing I don't think they can fix anything about GPS interference fly under a bridge in all the sudden you have interference sitting right there with respect to policy makers.
Yeah i'd like to see.
Policymakers get informed before they start making decisions that's a nice way to go and did you um did you approach the manufacturers with any of this you're gonna have to repeat that one more time did you approach the manufacturers with any of the vulnerabilities you know I I spoke to several people who were who wouldn't speak to me officially from parents are like we were designed to be open so people can do development both products came out on the market saying we have way . capability where you can program it for the Phantom 3 and 4 the bebop no you don't actually it turns out it's not there they market it that they had it and I'm like this is gonna be awesome I get it wait a second it's not there i can't find it i go to their forums and people have been complaining for months that parrot says you were going to get to it we're going to rely on third-party vendors to help us solve this problem and like well that's disappointing.
Phantom the Phantom to has way . that you can program the Phantom 3 does not so it would be nice if they got that moving along which would be helpful I haven't talked to anyone and DJ I did speak to someone who gave a presentation maybe an hour ago.
I said I kind of disagree with your statement that i don't have to accept to an update to a DJI phantom 3 and he goes out really i'll have to check on that.
Bad answer dude I suppose you get access with the ftp and then download the images and it turns out he actually has been taken pictures of your daughter and the shower where do you go with thank God I don't have a daughter say what ok suppose you did.
So he's taking a picture of me ok well i don't care he takes it but you've downloaded the picture it's obviously and inappropriate photograph that he's taken of a family member invasion of privacy you take that picture to somebody but what are your options legally etc.
What are my options legally it so what I'm not an attorney legally if someone more - peeping tom rules would apply at this point certain states are issuing privacy laws on drones it depends from jurisdiction to jurisdiction as to what's happening.
So the ideas at that point you go to the police and say hey dude my neighbor took a picture of me in the shower.
Through his drone and then you let them handle it and what do they say that you that the fact that you are absolutely you got the picture do they care about that or they made it open anyway so you can read this in a very nice respectful way of our law enforcement brethren usually when I tell them something like that they never get to that question.
Got it thank you they're off following the kid they they've never come back to me and said well how have you gotten a picture.
Well it was right there and I just took it here thank you it I noticed that a lot of the new manufacturers have invented the arm app in the controller they're running on Android have you checked any of that out do you have any future plans to see what Warner abilities are and I'd love to play with android right now I was focusing on the drone itself not necessarily the controller I just happened to peek into my ipad my iphone just to see what was there.
I have to think android is going to be very similar similar but then again when he's flying I'm not looking to disrupt his controller.
I won't take a look at the drawing itself ok just curious that's cool but I like the idea I just haven't gotten to it yet and it's been come a very expensive research project crashing groans my own drones I found it quite interesting that with both the bebop in the DJI you were able to connect another thing in flight I could not do that to the DJI phantom 3 I could do that to the parrot from okay that that that is actually pretty good I've noticed that a lot of drones have kind of paper availability of connecting and flying over security.
That's true with you know the bebop there and you know II even with some of the open source stuff if you're not using an Aes encrypted radio.
What do you think.
Are there except for.
Manufacturers to take in terms of securing their groans so that they can't be taken over mid flight.
It depends on what is being used for right if you're going to do hobbyist work and you're flying indoors i mean i think it would be great if we hung a couple minutes here and drone races I mean I would be fantastic everyone show up with your own you know.
Do It Yourself drone will zip around see who takes out the wall takes up the goons right and in that situation I'm not really concerned outside but I mean you can apply the same logic to other things in our society right.
Oh my god someone has a gun he could use the gun to do anything right.
What are the gun manufacturers going to do to prevent some guy using it irresponsibly right so we the same sort of thing here now if we're not careful and if the community doesn't put in the appropriate self guidance right you know Congress is going to legislate the hell out of it if it moves Congress will attack it if it makes the press so I think there's a limit as to how far we should go otherwise will completely kill the market it won't be fun anymore.
Thank you for the talk always welcome thanks for coming I was wondering on my scene that's your presentation was very focused on non.
Vulnerabilities and exploitation as far as a Wi-Fi based on some devices have you researched anything to do with securing your own personal drone you know i had my first thing to do is to see what i can do to knock it down the next thing I'll do to see what i can do to shut down particular services while he flies to make it a little more bulletproof bulletproof.
I just haven't gotten to that yet up on to add on that would you be interested in finding out by times afterwards.
Sherman Oh email address on the end of the last slide in the presentation drop me a line thank you were going to be the presentation drop me a line cool thank you very much.
He's good.
I just have one more question regarding to be played around it all with a dsb ok.
I have not are you familiar with that and not not so i can speak intelligently on it ok what happens if you fly the defense team through a magnetic field instead of having one you know around it so it can't take off if it flies through a strong magnetic field what happens.
I haven't tried it yet but if interference to gps is similar to the magnetic field I imagine it loses a lot of its finesse the DJI phantom 3 has a lot going for it I mean it is not a lightweight product i mean it has a ground sensor.
It has a ground facing camera it has a barometer it has a man magnetometer magnet in there it's got GPS so if i take out just one of them.
I assume that whole thing is still going to be flyable without any issue or with minor issues the problem is what happens when you get close to another object or a wall and then you have the extra air and then you lose that stability that's when I think you're going to run into problems I just haven't found a way to take a magnetic field and projected this thing wallet in flight I'll get to it right after I do my DeLorean and get it up to 80 miles an hour.
I'm going to find a way to project a magnetic field into a particular spot but when around his head and take care of that I i would prefer you don't project a magnetic field of my head but thank you.
Alright so if anyone else any questions we will take Michael out to the chaos that is the hallway.
I want to thank you that was awesome thank you i'm actually on behalf of speaker operations order is that you with that badge.
