Replay Attacks

Test if the device is vulnerable to replay attacks.

Concept​

  1. Capture legitimate traffic
  2. Replay exact same packets
  3. Observe device reaction
# From Wireshark capture
captured = bytes.fromhex("7e0404010001ff00ef")
char.write(captured).wait()
# If device reacts -> Vulnerable!
Next Step

Continue with Authentication Bypass.
