He takes great pleasure in staring at a “green” screen to help develop tools and hacks. Since he was young he was always interested in mainframes and has written multiple tools to help test their security. He has written applications in REXX, Python, C and contributed to John the Ripper, Ettercap and (eventually) metasploit. He runs a github repository for all things mainframe and collects tools from mailing lists, investigations and ones he’s built. Besides writing tools he’s given talks at multiple conferences including: BSidesLV, Thotcon, Shmoocon, DEFCON, BlackHat, ISACA and SEC-T in Sweden.
