In this fascinating exploration, Andrew Bellini dives into the world of IoT security, specifically addressing the question: Can you hack a car with a Flipper Zero? The answer might surprise you—you don’t even need a Flipper Zero to perform such hacks. Andrew demonstrates how to build your own device from scratch, showcasing the power of replay attacks and other hardware hacking techniques.
Andrew, a hardware hacking expert, is also the creator of the Practical IoT Pentest Associate (PIPA) certification, a program designed for those interested in IoT security. If you’re intrigued by the possibilities of IoT hacking, this certification is a great way to deepen your knowledge. Learn more about the PIPA certification here: https://lnkd.in/eqk3mkJy.
Practical Code and Commands for IoT Hacking
Here are some practical commands and techniques to get you started with IoT security and replay attacks:
1. Sniffing RF Signals with RTL-SDR
Use an RTL-SDR dongle to capture radio frequencies.
rtl_sdr -f 433000000 -s 1000000 -g 40 -n 1000000 capture.iq
2. Replay Attacks with HackRF
Replay captured signals using HackRF.
hackrf_transfer -t capture.iq -f 433000000 -s 2000000 -x 47
3. Analyzing Signals with Inspectrum
Inspect captured signals for patterns.

4. Decoding Signals with GNU Radio
Use GNU Radio to decode RF signals.

5. Building a Custom Replay Device
Use Arduino or Raspberry Pi to create a custom replay device.

void setup() {
pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
delay(1000);
digitalWrite(13, LOW);
delay(1000);
}
6. Testing IoT Devices with Nmap
Scan IoT devices for open ports.
nmap -p 1-65535 -T4 -A -v <IoT_Device_IP>
7. Exploiting Vulnerabilities with Metasploit
Use Metasploit to test IoT device vulnerabilities.
msfconsole use exploit/linux/iot/exploit_name set RHOSTS <IoT_Device_IP> exploit
8. Securing IoT Devices with Firewall Rules
Add firewall rules to protect IoT devices.
sudo ufw allow from 192.168.1.0/24 to any port 80
9. Monitoring Network Traffic with Wireshark
Analyze network traffic for suspicious activity.

10. Hardening IoT Devices
Disable unnecessary services and update firmware regularly.
sudo systemctl disable <unnecessary_service> sudo apt update && sudo apt upgrade -y
What Undercode Say
IoT security is a rapidly growing field, and understanding the vulnerabilities in connected devices is crucial. Replay attacks, as demonstrated by Andrew Bellini, are just one example of how attackers can exploit weak security measures. By building your own tools and learning how to defend against such attacks, you can stay ahead in the cybersecurity game.
Linux and Windows commands play a significant role in securing IoT devices. For instance, using `nmap` to scan for open ports or `ufw` to set up firewall rules can help protect your devices from unauthorized access. Tools like Wireshark and GNU Radio are invaluable for analyzing and decoding network traffic and RF signals.
For those interested in diving deeper, the Practical IoT Pentest Associate (PIPA) certification offers a structured path to mastering IoT security. You can learn more about it here: https://lnkd.in/eqk3mkJy.
In conclusion, IoT security is not just about understanding how to hack devices but also about learning how to protect them. By combining practical skills with theoretical knowledge, you can become a proficient IoT security expert. Whether you’re using Linux commands to harden devices or building custom tools for penetration testing, the key is to stay curious and keep learning.
