Attack Scenarios

A red teamer can use the HackRF One to do some tricky things with radio signals.

  1. Jamming: How it works: Overpowering legitimate wireless signals (like Wi-Fi, Bluetooth, cellular) with stronger interfering signals. Impact: Disrupts communication, prevents network access, and can interfere with critical systems (e.g., emergency services).
  2. Eavesdropping: How it works: Red teamer can intercept wireless transmissions (like Wi-Fi, Bluetooth) to capture sensitive data (passwords, conversations). Impact: Theft of personal information, corporate secrets, and financial data.
  3. Signal spoofing: How it works: Mimicking legitimate devices or signals to trick other devices into trusting or interacting with the attacker. Impact: This can be used for GPS spoofing (misdirecting navigation), intercepting communications, and gaining unauthorized access to systems.
  4. Replay Attacks: How it works: Red Teamer can capture legitimate wireless signals (like keystrokes and authentication data) and retransmit them later to gain unauthorized access. Impact: Bypassing security measures, unlocking devices, gaining control of systems.
  5. Hijacking: How it works: Red Teamer can take control of a wireless device (like drones and smart home devices) by intercepting and manipulating its control signals. Impact: Loss of control over the device, potential for misuse (e.g., crashing a drone, controlling a smart lock).
