Joe Grand, also known as Kingpin, is a computer engineer, hardware hacker, former DEF CON badge designer, and proprietor of Grand Idea Studio (grandideastudio.com). He joined the L0pht as a 16-year-old in 1992. The youngest member and technological juvenile delinquent, the L0pht kept him out of trouble and helped redirect his passion towards good. Kingpin worked on the POCSAG Pager Decoder Kit, AMPS-based cellular phone hacking, and Palm OS application development, among other things. He was also a t-shirt shipper, food picker-upper, MIT Flea Market hawker, and terrified speaker at the US Senate Testimony in 1998. Kingpin was responsible for getting everyone sick in his attempt at making the infamous L0pht R00t B33r. He still hasn't apologized.
