Here, I'm explaining how I solved my issues.

Why ?

This project is a direct continuation of my Wifijammer experiments. I have a strong interest in wireless communications and protocols like Wi-Fi and BLE, which drives me to test these vulnerabilities firsthand.

Moving forward, I plan to explore more advanced attacks and further deepen my understanding of these protocols to better comprehend how modern wireless security layers interact.

This report explores the vulnerabilities of IoT devices through SDR techniques. Conducted at Sorbonne University, the project addresses the inherent risks of radio communications, where signals propagate in open space, making them susceptible to interception and jamming.

The study utilizes a Raspberry Pi platform equipped with RTL-SDR and PlutoSDR hardware to analyze devices operating on various frequencies. Key experiments include:

Replay Attacks: Intercepting and re-emitting fixed codes to control smart plugs and roller shutters using tools like 433Utils and URH.
False Data Injection Attacks: Manipulating weather station displays by injecting forged temperature frames.
Advanced Signal Analysis: Moving to the 2.442 GHz band to reverse-engineer drone communications using GNU Radio, which involved bypassing XOR encryption and calculating CRC to retrieve a hidden flag.

The project demonstrates that many consumer IoT devices remain fragile due to the use of simple modulations (ASK/OOK) and the absence of protective mechanisms such as rolling codes or robust encryption.

I'll post the full code on GitHub with more technical details. 
Here, I'm explaining how I solved my issues. 
I'm learning to use aircrack so, 
I will not implement deauthentication to not lost my time.

Wireless Security Research : 802.11

I wanted to learn the basics of WiFi network attacks, so I started experimenting with deauthentication and beaconing. Beaconing is interesting because it relies on user interaction. I enjoy creating personalized clones that mimic real-world services; for example, it was fun rebuilding a fake Moodle login page for a French university. After using Aircrack-ng for deauthentication, I decided to focus less on the attack itself and more on improving the realism of my phishing pages. My next steps are to link these fake Access Points (APs) to the pages and implement a small DNS service to redirect all connections to the correct authentication portal.
