From my experience at Ben Gurion airport...security there has different stages. When you first walk in to the airport, even before you check in and get your ticket, some friendly attractive person will start chatting with you and ask about your trip. They will not identify themselves (or be dressed) as security. Your friend might very well have mentioned something to that person.
Later, when the more formal security process/interview starts, they might ask followup questions based on info they got from that earlier "interview".

This is interesting, where can I read more about this?
Yup. You'd be surprised what comes out of your mouth if someone attractive and personable starts smiling at you and asking questions randomly. You don't have your "defenses up" and you start blabbing away before you figure out that no, this person is not actually trying to hit on me :-)
With good reason, I can imagine how paranoid that would make me. I'd definitely try to find how they found this out, starting with checking whether I posted it somewhere public. That would be the least worrisome scenario.
