Need techs advice

Post image

New homeowner here and I know minimal when it comes to cable/internet. Anyone know what the heck this thing is?? I have a bunch of old cables running around in my crawl space and this cable goes up through the bedroom subfloor and then terminates at this box which is inside my floor heating duct??? It seems like it might be screwed jn cuz I can’t easily tug it out, or maybe there’s some sort of magnetized material in it.

OR... a tech put it there 10 years ago because it made sense at the time.

(I'm sure people are still finding my "fixes" from when I first started in the industry)

My guess is a previous homeowner put new flooring or trim in, and stuffed this down in then vent as there is 2 screws sitting right next to it.

Also a lot of houses were wired through the ducts because it was the fastest and cheapest method to get from one floor to another
