Due to the fact that Positive Hack Days is a forum devoted to the issues of practical IT security, the competitive program contained competitions of practical nature (for example, a contest related to searching information hidden in the Internet and hash cracking).
One of the competitions, where not only your head but hands could work, was a contest named 2600, in the course of which the participants had an opportunity to demonstrate their skills in phreaking and to hack a coin-operated telephone. Any visitor of Positive Hack Days could partake in the competition. The participants were to call a predefined number from a coin-operated telephone using tokens as the means of payment and then extract the used token and give it back to the organizers.
