The Dialed Up song is also a mini-CTF that is completely self-contained in an .mp3 file. The song has a load of phreaking related sounds and samples including a few dozen ring tones, rotary phone sounds, modems, carrier messages and DTMF. The mini-CTF is jeopardy style with around 7 challenges and will have a teaser version available early July and the full contest will be released the week of Black Hat and Defcon.
