What is referred to by the visibility of a threat actor?

The concept of visibility of a threat actor refers specifically to their intention to escape detection while conducting their activities. This means it encompasses the strategies and behaviors employed by the threat actor to remain hidden from security measures, law enforcement, or potential targets. A threat actor that values their visibility is likely to take significant care in how they design their attacks, manipulate information, and cover their tracks to avoid being caught.

This contrasts with the other choices: skill level indicates competence but does not directly relate to visibility, while tactics and methods, although they may influence how visible a threat actor is, do not specifically define their intention to be undetected. Additionally, "how it operates" may describe the functionality and mechanisms of a threat actor's behavior, but again, it does not address the aspect of intent to remain inconspicuous. Thus, the focal point of visibility aligns closely with the concept of concealing one's activities, making the choice about the intention to escape detection the most accurate representation.
