HackRF One

Use: Radio signals are sent and received by software-defined radios (SDRs).

• Signal interception: HackRF One is a tool used by ethical hackers to listen to and decode wireless transmissions. It is employed in the testing of communication systems, including satellite communications, automobile key fobs, and pagers.
• Replay attacks: To find out if the system reuses the same code, which is a common vulnerability, testers can record a signal, such as from a garage door opener, and play it back.
