In 2005, it was announced that "Phrack" was to come to an end, with the 63rd issue as its last. To commemorate "Phrack"'s final appearance, this issue was to be a hardback edition, released simultaneously at the DEF CON and What the Hack conventions on July 29. An e-zine version of the release followed on August 1. The European printer for the hardcopies of "Phrack" to be distributed at Defcon refused to fulfil the order once they realized that they were printing a Hacking book. Two University of Arizona students filled the gap and printed between 100 and 200 copies of "Phrack" 63 in time for release at Defcon 13.
