David Petraeus and his mistress were using the same trick: https://www.washingtonpost.com/news/worldviews/wp/2012/11/12...
In that movie, which I just check the date for, seems like one of the first pop references to the idea of sharing email drafts in a free email account without sending anything.

Now, can someone prove me one better and find where this idea got traction? I honestly laughed watching that movie, wondering if Petraeus watched it years earlier, and thought to himself, I wonder if this will work in real life ...
UPDATE: I could, gee, also try RTFWPA! It refers 2005 reports of AQ using the same tactic, you know, where probably he got it from.
Or he got it from the movie, which would make me in a die a fit of laughter!
Note that that doesn't mean it's GOOD.
Oh crap, mission compromised! SIGABRT! Wait, is everyone in this room part of the hacker cell? Are we all hacking each other? Haha.
(Honestly, what disturbs me the most is that, yet another spoiler, he puts all these suicide bombers on a bus to detonate themselves. And they never mention the bus driver who dies as part of this ruse. Not even does Don Cheadle seem to care about this guy! I found that pretty disappointing. I think that is just the underappreciated IT guy talking.)
