The best answer is D. Submit the device to the security team without connecting it.
An unknown USB drive found in a parking lot is a classic example of a potential social engineering or malware delivery attack. Attackers may intentionally leave infected removable media where employees will find it and plug it into a system. The safest action is to not connect the device at all and instead turn it over to the security team for proper handling.
Why the other options are incorrect:
A). Notify the file owner after reviewing the contents of the drive.Reviewing the contents requires connecting the drive, which could infect the system or trigger malicious code.
B). Use an air-gapped system to open the files without exposing the network.Even an air-gapped system can be put at risk. Regular employees should not analyze suspicious media on their own.
C). Wipe the drive immediately using a secure method.This destroys possible evidence and still requires handling the device in a way that may not follow incident procedures.
From a Security+ standpoint, removable media from unknown sources should be treated as suspicious. Proper procedure is to avoid connecting it and escalate to the security team. Therefore, D is the correct answer.
