This is very common in modern dwellings. Armored cable / MC is not necessary in your case The area with the moisture stains is the attic opening. Technically yes. There should be several feet of distance from the opening to the romex. For me this is a minor maintenance issue for an electrican to relocate the circuit cable to the proper distance (unless new construction then it would be a major because of the current code violation) I noticed this exposed wiring coming up from the service panel and going across the exposed joists in the garage before entering the attic through the firewall into the house.

Placing a fold of electrical tape over the end of a unused wire is fine in a temporary situation, but not as a long term solution.
