The intent is to have the user utilize the removable media on a system where the adversary is trying to gain access.   
DetectionDetectable by Common Defenses (Yes/No/Partial): No
Explanation: From a technical perspective, detection of an adversary disseminating removable media is not possible as there is no technical element involved until the compromise phase. Most facilities generally do not perform extensive physical security patrols, which would be necessary in order to promptly identify an adversary deploying removable media to be used in an attack.
Difficulty for the AdversaryEasy for the Adversary (Yes/No): Yes
Explanation: Commonly executed technique by penetration testers to gain access to networks via end users who are innately trusting of newly found or available technology.
