5$ ARDUINO car key JAMMER DIY. Relay attack / keyless car hack / car hacking protection 

all the techs can be used both ways for good and for bad. If you use this jammer inside your car nobody will be able to remotely open your car. This is all because car manufacturers do not embeed sufficient security inside their products.

@@justanengineer5599 My car cannot be remotely opened because my key uses "rolling code" unless the/my cryptography has been compromised. Your talking about wireless keys then jamming my own key inside my car, then i wouldn't beable to operate it unless its already operational, simple solution is use a signal blocking pouch with my key inside everytime i dont use my car. Useing a jammer this way over the top, users might even jam others around them.

even with the cryptography on board your car can be easilly opened by the rolljam attack as long as your car is listening to RF. Yes, having the keyfob shielded all the time should break challenge-response sequence but still there is a time window when your last sequence can be recorded and further replayed when you are intentionally opening the car If you mount this type of jamming device for example under your car with the switch you can use it in some special circumstances.

@@justanengineer5599 Not my car...has some more tricks Lol Then with what you said the RF jammer is the same with the pouch, if i leave my car jammed i am liable to prosecution. Jamming frequencys is illegal. Jammers are easily detectable. Best option would be a cryptograph rolling code to switch the locking mechanism and use the wireless key for the start with both having to be operated.

this is due to powerbank issues that cuts off the power when the current is low. find another power source. It happened to me as well. find cheapest powerbank with no protections

I think this variable condenser may not help much. You may want to build the second jammer based on CC1101 board and Arduino Pro Micro 8MHz/3.3V

jeszcze nie probowałem dzieki za wskazówkę

Hey whats ya social ill pay u

@@JCPN180 ?

​@@gianniiky7899 he said he'll pay you to help/do it for him

unfortunatelly no, this jammer uses FS1000A module which has fixed frequency due to the SAW generator used. SAW generators are using quartz crystals tuned to single frequency.

check my new project on github github.com/mcore1976/cc1101-tool This is something for You !

it is sdr touch. but now there are other free applications like sdr angel or sdr ++

@@justanengineer5599thank you so much. One thing can we do replay attack using this app?

no. for replay attack see my cc1101-tool shown in my 2 latest videos

go to www.aliexpress.com you can find all the parts there : fs1000a module and digispark board. Also color cables for Arduino are there

the frequency will depend on module FS1000A whether it is for 315MHz or 433MHz

correct

@@justanengineer5599 but in the video ,u said that the frequency run a bit

This one no. You need something based on CC1101 chip

@@justanengineer5599 can you help me creating this chip? I can’t find your email how do I contact you? Thanks.

@@justanengineer5599 what do you mean based on ? i’m beginner but this only stuff that interest me please elaborate or point in right direction

it has to be made using some chip for 5GHz wifi like nrf24l01 for 2.4GHz.

​@@justanengineer5599 Okay, will do a search if I can find the right component. I am only intending to make this device for purpose of securing my laptop. Back in 2018, I have lost one of my laptops (the laptop never turned on after shutting down got toasted it seems), the hacker seemed to have messed around with the bios (rootkit level). I then ordered a replacement motherboard from aliexpress china for the same laptop, and it was too hacked when i was online (the hacker deliberately did things like moving cursor, closing windows, deleting files from USB drive curropting exe files of programs and they give installation errors etc, without even me touching either the mouse or keyboard). I then physically removed the internal wifi card (or anything of that sort), and the hacker is still able to have full control of my laptop (he/she intentionally does these things to make realize they have full control of my computer). I even turned off my router, but it still continued. I had the same experience with other "used" laptop i bought on facebook. These "compromised" laptops motherboard seems to have some sort of planted chip (disguised as other chips) (that are sending/emiting and receiving rf or any other hard to detect signals) to nearby routers (including neighbors ones) or even some radars or proprietary signal receiving devices through which the hacker launches these sophesticated airgapped attacks and is able to have full control of the machine even when every physical wireless card/adapter/cable is physically removed from this compromised laptop (airgap hacking). I also witnessed many times, hacker turning on the laptop (even when its lid was down and wifi card was physically removed). The hacker has full control of the machine right from the moment it boots (when the company logo appears in the beginning). Many times when i tried entering the bios mode, the hacker was able to switch through menus in bios mode and change settings without me touching the keyboard once. I am not aware of such a malware, rootkit that can give someone full remote access right from the bios boot onwards. Would be helpful if u have any experience in identifying how it happens and what can be done to secure my machine as I am primarily worried about my data that I dont want gone and being sold to someone (am learning web development, game design 3d and stuff). I have had my product marketing pictures, deleted/curropted (in GB's) I spent years taking them for my business. My 3d files, website designs have also been deleted many times in past.

well going through bios options means something as hidden remote keyboard is attached to the mainboard inside the laptop, there is no other explanation to it

Yes it may work this way

search in my latest vids for cc1101 modules

walkie talkie operates on 446 band. You need combination of my second jammer CC1101 based with RF amplifier. look here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vZcGP-O2GvQ.html

this is RTLSDR USB radio receiver. You may buy it at 15 USD

@@justanengineer5599 is it good as the original one?

you have to use RTL SDR USB dongle and a PC with an application like SDRSharp or SDR++ or SDRAngel to see if your radio module FS1000A generates jammimg signal on correct frequency. There is no other way

@@justanengineer5599 jednak działa. Użyłem innego powerbanka. Po przedłużeniu anteny zasieg siega do około 50m

elegancko ! spróbuj zbudować moje najnowsze urządzenie którym można sterować za pomocą telefonu komórkowego przez kabel USB OTG

chyba tak

musisz mieć oprócz zamka radiowego takze zwykły kluczyk do drzwi samochodu. W przeciwnym wypadku moze byc kłopot z wejściem do pojazdu

of course not it is for 433/315MHz. K and Ka are 24000+ MHz

The app was SDRTouch. You may also find its description in my other video

nope

Apparently you can if ypu use pylora and customise the code. As they are transceivers

yes but you have to write new code. It would be like completely different design

Got that done with the antenna. Just not the relay (yet) but replay. But it is also pointless as the person drives away and locks and unlocks again, changing the code. People unlock with intent to drive away. It's all about the challenge from the 125khz (door) to the key now. That's the only way. Roll jam and replays, relays are all pointless exercises. Just look good on the tube.

I am afraid you need to build it on your own

you can easily build it yourself for 5$

it is RTLSDR USB v2 dongle. Search for it on www.aliexpress.com

@@justanengineer5599 how can i contact to you?

my email is on the channel description page

4G works on many different bands from 700Mhz up to 2600MHz. How do you want to cope with that :-) ?

@@justanengineer5599 Better off with an expensive hack rf one or something

you can port this code easily just change the pin number

the app name is SDRTouch

​@@justanengineer5599what usb caputre device did you use name and model please i want to buy it

up to 50-100m. Depends on antenna quality that is attached to the FS1000A module

you do recording with URH and then implement the sequence manually in Arduino code

@@justanengineer5599 I record with the transmitter urh programmed to it?

watch the video carefully. 2 or 3 times.

co masz na mysli dokładnie ?

@@justanengineer5599 wybacz źle napisałem, w sensie czy można skopiować sygnał przez tą aplikację na smartfonie razem z tą antenką tak jak to miało miejsce na komputerze

to urzadzenie nadaje tylko pseudolosowy szum. Jak chcesz tym nadawac to polecam moj film o otwieraniu bramy garażowej ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jziWQA8Wvp4.html Owszem mozna tym nadac cokolwiek z modulacją OOK/ASK Na filmie jest ten sam moduł uzywany z tym samym Arduino Digispark

need to use RF amplifier. But the easiest way is to power the RF module from 12V

@@justanengineer5599 is there a video tutorial? sorry, I'm still a beginner

attach 12v to vcc

@@justanengineer5599 how to?

Use 12V battery for RC models: 12V + --> Digispark Vin 12V + --> FS1000A VCC 12V - --> DIGISPARK GND 12V - --> FS100A GND DIGISPARK PB2 / P2 --> FS1000A DATA

I am using SDRTouch full version in this video

yes

@@justanengineer5599 how about garage door with 330mhz? Can the 315mhz do the job?

no, for 320MHz you need my second jammer ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vZcGP-O2GvQ.html

Have you followed this tutorial startingelectronics.org/tutorials/arduino/digispark/digispark-windows-setup/ ? sometimes you need to use different USB port or even USB cable extender to make it work

this only jams the keys. Stealing is much more complicated...

i will try but it will not be anytime soon

Of course. You simply touch power grid socket with wet hand - this will disable the transmitter for sure :-)

@@justanengineer5599 be careful, some idiots may actually try that

@@tmpEngine Ideally, yes!

you can make it yourself its easy

@@justanengineer5599list all tools I need please sir❤

Please don't sell to this guy

Look for my other videos I have used CC1101. In this particular project you may use any transmitter supporting single DATA IN pin and on-off keying modulation

try to talk in my language :-)

Why because he's from north America? That's very sad you wasted your time to insult the guy but you watched his video 😂

The more you listen, the easier it becomes to understand.

Get a grip!

elaborate

Because you actually need a brain to do that😄

with arduino you can use pseudorandom bit stream to drive the transmitter. However this code is not making an advantage of this possibility

You can easly to record it and replay with Raspberry Pi and RPITX software that I am showing in my other video. It can handle frequencies from 5 KHz up to 1500 MHz. See this video here : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WmvEid3ULvE.html

The minimum is 500khz?

this was to jamm attacks

correct. shapes sizes and board color is not important. Important is to have 8 PIN connector and CC1101 chip on the board

@@justanengineer5599 can i use Attiny 85 digispark with cc1101 modules to jamm?

Unfortunately no. Believe me I have tried hard to make ATTINY85 work with CC1101 but I failed. The point is that ATTINY85 does not have full SPI BUS and I had a lot of problems.

@@justanengineer5599 one of ur video u made cc1101 and arduino pro micro for rf jammer which u said working in both 433 and 315 and others freqency is that right ?

correct. here is the video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vZcGP-O2GvQ.html

Nope. I am just an engineer showing you the weaknesses of your surroundings. I am doing it all for free

@@justanengineer5599 love it, I say “badass” in a respectful way 🙏🏽

​@@justanengineer5599thanks a lot

Yes but what if someone has already recorded your signal and is only waiting to replay it and open and start your car? then this jammer comes in to the rescue

Hi, the app is SDRTouch. The dongle is no name bought on www.aliexpress.com

Thank You very much. I left You a new question after I built the besutiful circuit. If You can tell me what went wrong since it works perfecto but Powers off sutomaticly after 10 seconds aprox. It does not execute the endless loop written in the INO file. Cheers!!!

you do not have to use this capacitor.

Yes. You simply need to power Digispark through Vin pin / GND pin instead of using USB power

yes, this one should work because it is a simplest ASK OOK transmitting module

Can i also use this? Digispark USB ATiny85 - Micro USB

yes you can

for other transmitters like CC1101 there is a different solution - look here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vZcGP-O2GvQ.html

Are you interested in tutoring?

depending on frequency, I am using simple whip antenna but the length is important. You may also purchase some 6dBi or 15dbi "directional antenna" for 433MHz/315MHz on Aliexpress if you solder SMA socket to this board

@@justanengineer5599 Thank you for the swift reply, would a wifi modem antenna work!?

Of course

@@justanengineer5599 tks

RTL SDR USB

Maximum range of FS1000A module is 100-150 meters. That strictly depends on power source voltage. In my case it was around 60-70 meters

Nice

@@justanengineer5599 whats the voltage can we use like the maximum
