Soldier of Fortran is a mainframe hacker. Being a hacker from way back in the day (BBS and X.25 networks) he was always enamored by the idea of hacking mainframes. Always too expensive and mysterious he settled on hacking windows and linux machines, until 2010 when he finally got his very own. Not worrying about system uptime he dove in head first and was surprised by what he found. He’s spoken both domestically (DEFCON, BlackHat) and internationally on the topic, developed tools for mainframe penetration testing and has even keynoted a large mainframe conferences on this topic.
