11 sections • 21 lectures • 1h 44m total length

00-Introduction1:18
Assess the security of wireless devices, sniff and transmit data, update firmware on a hacked board, and perform capture and replay attacks on wireless doorbells, switches, and first-person view cameras.

01-Radio Frequency Spectrum5:56
Explore the radio frequency spectrum from three kilohertz to 300 gigahertz, covering VLF, LF, MF, HF, VHF, UHF, and SHF bands and uses like submarines, GPS, Wi-Fi, and broadcasting.
02-HackRF ONE Board1:30
Explore the hackrf one software defined radio board, covering 1 mhz to 6 ghz, with half duplex operation for transmission or reception, antenna port, and variable output power.
03-Requirements1:00
Use the hackrf one board as the primary tool to receive and transmit frequencies, and validate reception with an sdr dongle to verify data.

01-What is FCC ID3:59
Discover how the FCC ID, a unique code on wireless devices, lets you locate their operating frequency via the FCC ID database, and find frequencies without the ID.
02-Check Wireless Doorbell frequency5:30
Learn to locate wireless device frequencies, like doorbells, by researching rough 400–500 MHz ranges and using HackRF One with Dragon to pinpoint 433–450 MHz.
03-Check Wireless Switch frequency2:33
Identify the wireless switch frequency with the gr and rf one device, focusing on 433 to 450 mhz; explore future replay attacks to control it.
04-Check Car Key frequency1:55
Identify the car key frequency with a HackRF One by scanning the 315 MHz range, noting peaks around 312–315 MHz, and look up other device frequencies with Google and Kcrw.
05-Wireless Doorbell Record and Transmit8:18
Record, analyze, and replay wireless signals with Universal Radio Hacker and HackRF One, configuring frequency, bandwidth, and gain to transmit the captured wireless doorbell signal.
06-Wireless Switch Record and Transmit5:19
Perform a capture and replay attack on a wireless switch using Universal Radio Hacker and HackRF One. Record the signal at the target frequency and replay it to transmit.

Description

Wireless devices are everywhere — from home automation systems to remote controls, IoT devices, and communication systems. Understanding how these systems operate is essential for cybersecurity professionals who want to assess and strengthen wireless security.

This course focuses on wireless security research using the HackRF One board, conducted strictly in controlled and authorized lab environments.

You will begin by learning the fundamentals of SDR and how the HackRF One operates. We will explore frequency ranges from VLF to EHF, understand wavelength relationships, and use spectrum analysis tools to visualize wireless activity.

Throughout the course, you will learn how to:

Analyze wireless signals in a lab environment
Study replay attack mechanisms conceptually for defensive awareness
Understand how vulnerabilities may exist in poorly secured wireless systems
Conduct safe signal transmission experiments in authorized setups
Evaluate the security posture of test devices created specifically for research

All demonstrations are performed on personally owned lab devices or simulation environments. No unauthorized interception, device exploitation, or illegal broadcasting is performed or encouraged.

The focus of this course is security awareness, vulnerability understanding, and defensive skill development, helping you responsibly analyze and secure wireless systems.

Disclaimer

This course is strictly for educational and defensive cybersecurity purposes. All demonstrations are conducted in controlled lab environments using authorized equipment. Students are responsible for complying with all applicable laws and regulations. Unauthorized interception, transmission, or interference with live systems is strictly prohibited.

Who this course is for:

Cybersecurity professionals interested in wireless security
Students learning ethical hardware security research
SDR enthusiasts who want structured and responsible training
Security researchers working in controlled lab environments
Anyone interested in wireless analysis using HackRF One
