The Punch Line Goes at the End
The Black Hat conference in Las Vegas always has its share of drama. This year, it’s happened a month before the conference opens. The researcher Barnaby Jack had to cancel his talk. Risky.biz gives an account of this; his talk was to make an Automated Teller Machine spit out a “jackpot” of cash, in the style of a slot machine.
According to reports, the manufacturer of the ATM pressured Jack’s employer, Juniper, to pressure him to withdraw the talk.
I certainly roll my eyes at this. It doesn’t do a lot of good to pressure someone to withdraw their talk.
But even more so, if you’re giving a talk, it behooves you to save the showmanship for the stage. I mean, come on.
Last year, the big cancellation was the team of MIT students who broke the Boston MBTA Charlie Card system. There was a legal injunction put against them that spoilt their presentation. The fault, in my opinion went to them for naming their talk, “How To Get Free Subway Rides For Life.”
Imagine that you are a judge who is interrupted from an otherwise pleasant Saturday by panicky people who want an injunction against a talk with such a dramatic name, you’ll at least listen to them. You decide that sure, no harm to society will come from an injunction from Saturday ’til Monday, and you’d be right. No harm came to society, DefCon was merely a little less interesting.
Now imagine that you are the same judge and you’re asked for an injunction against the talk, “A Practical Cryptanalysis of the Mifare Chip as Implemented in the MBTA.” That one can wait until Monday, and the talk goes on.
In a similar gedanken experiment, imagine that you are the VP of Corporate Communications for the XYZ ATM Corp. You learn that in a few weeks, someone is going to do “ATM Jackpot” with one of your ATMs in some show in Vegas. Despite the fact that someone else in the company approved it, what do you? You pressure them to cancel. Duh. If you don’t, then you’re going to spend most of August reassuring people about your products, your boss is going to be really ticked at you (after all, isn’t it the job of Corporate Communications to control these things?), and it’s just going to be no fun. This is also why you’re paid the big bucks, to make embarrassments go away.
This is why if you are a researcher, you do not name your talk, “ATM Jackpot” you name it “Penetration Testing of Standalone Financial Services Systems.” It is only on stage that you fire up the flashing lights and clanging bells and make the ATM spit out C-notes for minutes on end. That would get you all the publicity for your talk that you want, and you actually get to give it.
Remember, do as I say, not as I do. If you have a flashy Black Hat talk, put the punch line at the end of the joke.
