Скачать или смотреть Decoding IoT Signals with Software-Defined Radio and RTL-433

Summary
In this conversation, Michael Smith and Sam Schneider discuss RTL-433, a decoding software that can use a software-defined radio (SDR) to intercept and decode wireless signals from various Internet of Things (IoT) devices. They explain how RTL-433 works and its applications in capturing and analyzing signals from devices such as utility meters, tire pressure management systems (TPMS), and more. They also demonstrate how to use RTL-433 and the HackRF PortaPack H2 to capture and analyze signals in real-time. The conversation highlights the importance of understanding the signals and devices in our environment for security and remediation purposes.

Commands:
sudo apt-get install rtl433-sdr

Sound Bites
"Did you know that every day there are radio signals from IoT devices around you that you don't even know that are you know that you can take software and decode"
"all of your gas meters, electric meters, things like that, water meters now are actually running on this frequency and you'll actually be able to decode it and see some information on it"
"RTL-433 allows you to record samples and it allows you to do frequency hopping"

Takeaways
RTL-433 is a decoding software that can intercept and decode wireless signals from various IoT devices.
It can be used to capture and analyze signals from devices such as utility meters, tire pressure management systems, and more.
RTL-433 can be installed easily on Debian-based systems and provides a wide range of decoders for different devices.
Using RTL-433 and the HackRF Portapack, users can passively collect and analyze signals in real-time.
Understanding the signals and devices in our environment is important for security and remediation purposes.
