Matthew,
Yes, that is a low voltage transformer of some sort. More likely for the doorbell. And NO, they do not go inside junction boxes. That installation is typical. Most of the time a doorbell transformer will be attached the the side of the SE panel or somwhere on the wall within that area.
As for the wiring, You have a bunch of spaghetti nm romex wiring mixed in with telephone wiring throughout the attic. I just note in the report that exposed wiring (in attic) is not running through floor joists and may be pinched if walked on or if flooring is installed.
Half my attics here in Massachusetts resemble the same manner.

Certainly it is preferable to have all wiring in attics secured and safely out of the way.
In there are stairs or a ladder it is required.

320.23(A) Where Run Across the Top of Floor Joists. Where run across the top of floor joists, or within 2.1 m (7 ft) of floor or floor joists across the face of rafters or studding, in attics and roof spaces that are accessible, the cable shall be protected by substantial guard strips that are at least as high as the cable. Where this space is not accessible by permanent stairs or ladders, protection shall only be required within 1.8 m (6 ft) of the nearest edge of the scuttle hole or attic entrance.
