The Los Angeles Police Department has warned residents to be wary of thieves using technology to break into homes undetected. High-tech burglars have apparently knocked out their victims’ wireless cameras and alarms in the Los Angeles Wilshire-area neighborhoods before getting away with swag bags full of valuables. An LAPD social media post highlights the Wi-Fi jammer-supported burglaries and provides a helpful checklist of precautions residents can take.
Criminals can easily find the hardware for Wi-Fi jamming online. It can also be cheap, with prices starting from $40. However, jammers are illegal to use in the U.S.
We have previously reported on Wi-Fi jammer-assisted burglaries in Edina, Minnesota. Criminals deployed Wi-Fi jammer(s) to ensure homeowners weren’t alerted of intrusions and that incriminating video evidence wasn’t available to investigators.
back in the day, the trick was to cut the phone line, then shove the cut wire back in the phone box. wait for the police to come and see that there’s nothing wrong, then you go and burgle.
They’d be starving after waiting for 3 days.
That screen capture looks like the beginning of a rap video.
My cameras have antennas on them but use Ethernet.
Why did they specifically mention to “secure home DVR recorders”?
Other than potentially losing some TV or movies, is that really a big deal next to the other items they mention? It seems really odd to mention one of the least important things.
No. Think about it. Where is all the video from those cameras going? It is digital video, which the homeowner probably wants to record and playback… Many home security setups, particularly those that don’t rely on a cloud service, are basically a DVR back end with a security focused UI.
I’ve never heard of used outside of a cable box. I didn’t know security setups would be called that.
But with that information it makes sense.
You made me one of the 10k today
before getting away with swag bags full of valuables
So just look for the guy who looks like he’s just been to four different network admin conferences?
Bill, where did you get these 37 easy buttons?
Physical locks, physical keys. We are collectively becoming too “smart” for our own good
Not sure how that’ll help with doorbells and cameras not working?
Physical locks and keys are also easy to bypass.
I’m curious if these are actual jammers or just deauth devices.
It also seems really risky because I think we have three different bands Wi-Fi devices use now?
It’s all just radio signals.
Radio can be delightfully complex. I can’t help but be curious.
Oh I agree. It’s very cool stuff. It’s pretty amazing what we can do with it.
What do you mean actual jammer? If it puts out RF at a power level greater than the surrounding environment it is a jammer, correct? I would think for this attack to work you could just target the camera freqs used, you don’t have to target the whole home’s WiFi network. Probably a narrower range to focus on.
I don’t think it’s that simple. The newer Wi-Fi standards are broadband (something on the order of 1GHz wide!), so the required power spectral density to block Wi-Fi across all channels is pretty extreme. I don’t think you’re doing that for $40. We should also keep in mind the standards were designed to operate in environments with other unlicensed devices and in the presence of interference.
If you just want to target the frequencies the cameras are using, that would require a little bit of research skill that I think would elude most criminals. Also, some routers will change frequencies if the interference is bad.
If I were building such a device I would use off the shelf Wi-Fi hardware and send deauthentication frames to any nearby stations. But even with this approach, there are devices that will ignore such frames now because it’s been a problem.
WiFi 6 camera probably exist, but most will use WiFi 5 or lower. Theres only 13 channels and of those usually only 3 or ever used due to band overlap.
Lol. None of my smart devices will connect to anything other than a 2.5ghz connection. Only my TV will accept 5g. The range is MUCH narrower than you think. Then figure in that the top 5 or 6 companies provide hardware for 90% of peoples home installations and that pool becomes even smaller. Also, a microwave operates on the same frequency as 2.5 and was a common disconnection problem in the past.
This is trivially easy.
I wish that apps notified you when your camera has been unreachable for too long, but at least that’s a hint that a jammer may have been involved. Cameras won’t stop them, but a the best setups would rely on wires and hidden local and cloud storage for recordings and alerts.
Especially if X# of cameras are down
Amcrest’s app does, and you could do it yourself with something like Home Assistant.
Just picked up our 2nd bullet 4k with ai. It’s a good addition to my nvr.
apps notified you when your camera has been unreachable for too long
The volume of false positives this produced would render the system significantly less useful.
A numbers of cameras tell the user when they go offline, but yeah, a lot do not. I have a HomeKit system that sends an alert when WiFi or power has been interrupted to the camera or the primary hub.
The thieves are jamming WiFi systems and the comments on the article and on Lemmy seem to blame the victim for not being tech savvy. The bulk of Nest/Ring customers do so because the app is easy to use and the cameras easy to setup. By definition the victims are far less likely to be able to defend against this kind of jamming attack.
If the next step in escalation is to shut down the power to the house, will the victim be blamed for not having home batteries and solar panels?
Why not question the viability of WiFi systems in general? Has video ever been more than a deterrent to those scared of cameras? Fearless thieves who know how to deter the systems get free loot for their trouble.
Treat security like we did before 2010; improve physical security to defend instead of relying on deterrence.
LAPD is recommending cutting back shrubbery and coordinating with neighbors for extended leave… As a Los Angeles native, neither of these things happen. After all, high walls make for good neighbors.
He only says, ‘Good fences make good neighbors.’ Spring is the mischief in me, and I wonder If I could put a notion in his head: ‘Why do they make good neighbors? Isn’t it Where there are cows? But here there are no cows. Before I built a wall I’d ask to know What I was walling in or walling out, And to whom I was like to give offense.
I tried to get the formatting right, but oh well
I don’t know why everyone doesn’t do what I did. I have a WiFi doorbell camera but I also have 13 other cameras that cover the entire perimeter of my house connected to a PoE switch. My switch is on an UPS and connected to an outlet my natural gas generator cutover powers. My office (includes my miniPC running HAOS and frigate) is also on an UPS plugged into outlets my generator cutover powers in a locked cage inside a vented drawer with a 120mm exhaust fan to keep air circulation going in the drawer. All motion is recorded and saved to my local NAS (that is in the same locked cage) for 30 days and it syncs the recordings directory to the cloud. I have isolated cameras that look like usb chargers that record motion on a loop to 128GB micro sd cards aimed at all entry/exit points, hallways, and points is interest. Everything is pretty much set it and forget it. I get notified of any motion on my property regardless of my location and the jpeg captures are immediately sent to a dedicated email I setup should something unforeseen happens to the recorded video. If my or my partners cell phone is not on the WiFi all the cameras (except the doorbell and isolated ones) are set to siren mode on movement detection and they are surprisingly loud especially if two or three are going off at once.

Is this something you coded, or are there security camera brands that support it natively?
The only part I coded was sending the api calls to cameras to turn on/off siren mode. I relied on a lot of other folks reverse engineering to help me along.
I don’t know why everyone doesn’t do what I did.

Your setup is fucking insane, and I mean that in a good way. As someone who ran a small team focused on security and who entertained more than one “I totally sploited our OS/let me show you how we suck today so we can fix it” conversations with dizzyingly smart zealots, this setup has excellent layering and coverage. Well fucking done.

Cost. The same people who say “I’m on a pension so they can’t steal much from me” without realizing their retirement savings and credit rating are the golden fucking goose, also won’t see the benefits to such a cost in capital and setup labour. They won’t do it, and they’ll see us as nutcases until the leopards have eaten their face.
I very much doubt they genuinely have all that, this is pretty obviously sarcasm.
Also, thank you, that’s nice to hear from someone in that line if business
I was making a joke using the absurdity of what I put together as a hobby project over the past couple years as an example to reinforce the comment I replied to. I’ve spent my whole career in IT and it’s absurd the level of knowledge a lot of career or even hobbyist IT folks expect the general public to have.
My generator cost $8k installed.
I ran all the cables myself, still cost $1k for the materials.
Doorbell camera $200.
PoE cameras averages to $174 each or ~$2,500
UPS’s: $300 combined
MiniPC: $500
Cage and mounts: $150
Isolated cameras: $30 ea
SD cards: $15 ea
All told I have over $13k invested easily and it would easily be over twice as much without knowing how to do it myself. Anyone giving folks shit for using WiFi security systems is out of touch.
Fence with a lock on it is a lot cheaper. Crazy how much people will spend on surveillance, given how little it does to achieve deterrence.
I got insurance. I’d help load the truck rather than get shot if someone broke into my house and I was home. This has mostly been a fun project hobby that I can continuously tinker with while working in my office from home. I’ve had a lot of trouble finding a hobby I’m able to stick to that is mentally challenging and rewarding to me. The progressive learning has been great and has me excited to continue with further integration. That said. I will have evidence for police and insurance. I also enjoy watching the deer and other wildlife without going outside which tends to change their behavior.

You’ve absolutely nailed the smug tone some of the comments here have, good work.
Also, imagine explaining all that to my mum, you’d be there all week.
You just said HAOS and Frigate, and “set it and forget it” in the same statement. As a long time user of both I call shenanigans.
I also think you overestimate the ability of the average person. My mom barely knows how to work her Ring doorbell camera.
That was one of my attempts at playing my hand that I was being sarcastic. I tinker with the shit weekly and yes it is way beyond what any reasonable person should be expected to invest or understand. It’s just become a hobby of mine and I was trying to be funny, which I’m not very good at.
Family members will think twice about masturbating in your house.
Nah, they’ll just do it while staring directly at the camera. Gotta get that eye contact.
Can’t go wrong with a german sheppard.
Until he gets bored and starts gnawing on the linoleum
Yeah, it’s not really a spike in burglaries so much as a spike in a specific tool being used in burglaries. Whether they use a brick, wifi jammer or a gun they were going to rob someone someway…
Or a hoodie. I’m not sure why it’s a big g deal to WiFi jam a video doorbell when you can also defeat it with a hoodie …. Plus that’s not a burglar alarm.
Whoever is peddling anything as a burglar alarm that depends on WiFi is the real criminal
i know nothing; would a hardwired connection from the cameras to the router solve this?
Yes but the camera should be in a place that can’t be physically tampered with easily since someone could theoretically unplug the camera and plug into your home network and see all your computers or other devices as if they had stolen your WiFi password. A small risk but it’s better to hardwire it somewhere they would need a ladder to get to or get a camera system that connects to a central box inside the house.
Well, if it’s not on a WiFi network, it’ll be fine. CCTV is a great example of this. Just wire up some cameras, encrypt the harddrive and put it somewhere difficult to get to. Only way to disable all cameras at once would be an EMP. There are kits for a few hundred $ and all the data stays local
Or just flip off the main switch on your breaker if they can get to that.
Totally. Get a PSU? Or use solar with a PSU. Or batteries. Always a mitigation for the mitigation lol
yes, assuming the cables are inaccessible from outside. otherwise it would be easy to cut them.
If you are close enough to cut cables, they already have you on video.
Yes.
That’s one of the reason I went with a PoE camera. Just make sure your network is isolated so people can’t connect to your internal network from the camera Ethernet cable.
Or vice versa, connect to your cameras from the rest of your network.
It doesn’t hurt to hide or disguise the cameras to make them difficult to spot. That way, burglars wouldn’t even try to find and break their server if they’re not noticed.
However, jammers are illegal to use in the U.S.
What is the point of adding this bit for an article about burglaries?
Ostensibly harder to obtain when they’re illegal to stock and sell retail.
Same reason why you see folks in Japan and the UK obsessed with knife crime rather than gun crime. Obtaining a gun is more difficult to do legally, so fewer people carry them.
They’re extra illegal!!!
They should make burglaries illegal too!
Because it’s relevant? Is this not factual information that readers may or may not have known?
The availability of hardware changes by a not-negligent degree based on the legality of acquiring it.
Curious readers likely find information indicating that these shouldn’t be readily available at your local big box store to be pertinent information.
It does and it doesn’t.
Any microwave with the door rigged open is a super effective Wi-Fi jammer. Everything coalesced on 2.4GHz instead of licensing their own radio spectrum making absolute mountains of overlap. It’s harder jam nearly everything else. ( Not much harder, software radios are super cheap, but you at least need more electronics knowledge than a screwdriver and tape. )
Because jammers are not inherently burglary tools. It provides extra information about the technology in discussion.
Because Californians love writing laws as a knee jerk reaction to the crime de jour.
Some pearl-clutching local will go to their state legislature and demand that WiFi jamming be banned despite the fact that the FCC is all over that shit. They keep passing redundant gun control laws in the same way for the same reasons.
While I don’t dispute that California has a tendency to have obnoxious firearms law:
https://legalbeagle.com/7402613-california-sword-law.html
Surprisingly, it’s entirely legal to carry a sword in public in California, as long as you are the wearer is not brandishing it or concealing it. In other words, if the sword is carried in a sheath suspended from the wearer’s waist, it is legal to have in public.
That being said, from memory going through California’s code, I believe that they explicitly have katana restrictions, along with some other restrictions on Japanese weapons, probably for the same reason that a number of states have switchblade restrictions: there were movies that hyped up the “gangster” aspect.
kagis
Hmm. No, and it looks like the nunchucks ban was repealed during the last few years, so they may have re-legalized katana carry along with that.
https://usanunchaku.com/california-legalized-nunchaku/
For over 50 years the state of California has made nunchaku illegal or restricted to only state licensed martial arts schools. As of 9/30 2021 this restriction in California has been repealed with the passing of CA Senate Bill No 827 and has resulted in California Legalized Nunchaku for everyone.
Now all California residents may purchase nunchaku without restriction or needing to be a member of a martial arts school training in the art of nunchaku. Here at American Nunchaku Company we welcome our new and old Californian customers and invite you to stop by and check out our collection of custom handmade nunchaku.
Shruikens – ninja stars – remain banned in California, though.
One can but imagine the plague of ninja being held back by this legislation.
Something tells me that systems will just have a strong dummy wireless signal act as a tripwire and then it goes down, it triggers stuff…even super low end stuff could implement it.
Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.
A massive net to catch the baddies
Worked at an old job where one guy, that had access to the router settings, would disable the Blink Cameras so he could forge his time cards.
Owners ended up realizing the cameras would only be disabled when he was on shift.
I worked at Walmart ages ago and one of the overnight assistant managers would do this and then steal cash out of the cash office until he finally got caught.
My August lock wifi goes down like 4 times a week. I feel so safe.
Wish it had an Ethernet option, not sure how that would work on a door though lol
Wish it had an Ethernet option, not sure how that would work on a door though
You’d just run a cable to the door from the hinge side, preferably inside the door through the hinge so it’s not visible on the door itself. This is a very common solution for electronic locks in office buildings for example.
