Question 90
An attacker pairs with an exposed legacy Bluetooth service while the target phone is discoverable in a crowded venue. What surface is exploited?
Explanation
Correct Answer
Weak local-radio authorization can allow unintended proximity access. For this case, an attacker pairs with an exposed legacy Bluetooth service while the target phone is discoverable in a crowded venue. Prioritization should consider exploitable exposure, asset importance and remediation feasibility; a detector or workaround is not automatically equivalent to repairing vulnerable code. The competing choice “A malicious container image registry” addresses a different mechanism: no software image was downloaded or executed. That difference is material to the requested decision.
Incorrect Answers
No software image was downloaded or executed. An attack vector describes the channel or trust boundary used for initial delivery; it should not be confused with the payload or ultimate attacker objective. Here the decisive fact is an attacker pairs with an exposed legacy Bluetooth service while the target phone is discoverable in a crowded venue. “Short-range wireless pairing and service exposure” matches that requirement because weak local-radio authorization can allow unintended proximity access.
The event does not involve payment email identity. An attack vector describes the channel or trust boundary used for initial delivery; it should not be confused with the payload or ultimate attacker objective. In the reported situation, an attacker pairs with an exposed legacy Bluetooth service while the target phone is discoverable in a crowded venue. The effective mechanism is “Short-range wireless pairing and service exposure”: weak local-radio authorization can allow unintended proximity access.
The attack is over Bluetooth rather than offline storage handling. An attack vector describes the channel or trust boundary used for initial delivery; it should not be confused with the payload or ultimate attacker objective. Here the decisive fact is an attacker pairs with an exposed legacy Bluetooth service while the target phone is discoverable in a crowded venue. “Short-range wireless pairing and service exposure” matches that requirement because weak local-radio authorization can allow unintended proximity access.
