A BLE attack captured LL_ENC_REQ and LL_ENC_RSP packets but not the LTK.

In CEH v13 Mobile, IoT, and OT Hacking, Bluetooth Low Energy (BLE) attacks often involve capturing pairing exchanges. If the Long-Term Key (LTK) is not captured, decryption is not immediately possible.

CEH v13 explains that in such cases, attackers may attempt Btlejacking, which hijacks an existing BLE connection rather than decrypting it. This allows command injection and data manipulation without needing the LTK.

Options A and B are incorrect because decryption is not the only attack path. hcitool is for discovery, not exploitation. Therefore, Option D is correct.
