T-Shirt Shell Competition

For our internal hackathon, we wanted to produce some shirts. We ran a competition to see who could produce a reverse shell invocation most worthy of inclusion on a shirt. Here are the submissions, which may be instructive or useful. But first; the winning t-shirt design goes to Vlad (-islav, baby don’t hurt me, don’t hurt me, no more): Funny story; the printer left out the decimal points between the IP, so we had to use a permanent marker to put them back. Oh, also, many of these were originally taken from somewhere else then modified, we don’t claim the full idea as our own. Anyway, onto the shells!
