Soldier of Fortran (SoF) use to work as an auditor and was thrown into the lions pit of mainframes with very little support. He heard how secure it was, assumed everything worked as described and never questioned the system programmers. That was ten years ago. In those ten years he’s dedicated himself to mainframe security research. No longer satisfied with always being told how secure their systems are he started to develop tools, workplans and attack vectors to really see how secure they were. In 2012 he submitted a talk to the proving ground track at BSidesLV and was accepted. Since then he’s given talks about mainframes at Thotcon, BSidesAustin, Shmoocon and BlackHat! Don’t fear, he hates giving the same talk more than once and never presents the same talk twice!
