At the entrance at What The Hack the crew has placed an x-ray security scanner (you know, one of these they use at airports) for the people to play around. But when the system was first setup it asked for a three digit passcode.
The quick decision was to brute-force the system and to just get a bunch of motivated people trying out ten numbers each. Well, everything worked according to Murphy’s law, which means that they had to try out more than 90% of the numbers before finding the right one.
“So what was the code”, you ask?
We could have guessed it: it was 911.
