Cybersecurity & Hackers: Can You Hack a Robot?

At a robotics tournament, 100 geeks are in one room. The Wi-Fi is crowded. Could a malicious team “Hack” an opponent’s robot to make it stop?

The Attack Vector (Wi-Fi Deauth)

The most common attack isn’t “Coding a virus.” It’s a Deauth Attack.

• The hacker sends a fake packet to the router: “Hello, I am Robot 1234. I would like to disconnect.”
• The router says: “Okay, bye.”
• Robot 1234 stops moving.

The Defense (WPA2/3)

To stop this, we use Encryption.

• The robot and driver station share a secret password.
• Every message is locked.
• If the hacker sends a “Disconnect” message, the router ignores it because it doesn’t have the secret signature. Cybersecurity is an arms race. But in FTC, the biggest threat usually isn’t hackers—it’s just forgotten passwords.
