I'm surprised Mossad didn't extract her before this. I figure the FBI finally found her through phone taps on people she knew, then set up surveillance to narrow down to her physical location the next time she used a phone. The use of the LLC to hide her is pretty much spy tradecraft. I am surprised that she was not guarded by Israeli nationals. The use of foil to cover the phone though was a slip in tradecraft, probably because she is a socialite type and not an active field agent who would know better. A casual foil wrap is imperfect as an RF shield, and it can leak. A microwave oven definitely leaks, too; all it does is reduce levels but it doesn't completely eliminate. Sometimes you can light an NE-2 bulb if the door seal has any food on it.
