I seen this post and thought it was interesting, Something none of you have mentioned as far as being able to tap into a customers data you wouldn't need to ever touch the fiber Now I have never had FIOS but based on the ONT's they have a ethernet jack you could easily put a splitter there and have access to their network. someone correct me if im wrong, Like I said ive never had FIOS so that doing it that way might not be possible.
Very valid statement and ethernet sniffing is easily done. For most installs the ONT is within the user's premises, so physical access has to be gained inside the home/facility. There are times that they are installed externally, but once again physical access close to the user premises has to be gained.
