 gorio \, Independent Security Researcher\n   Jay Lagorio\, a software engi
 neer and independent security researcher\,\n   has been building computers
  and networks and finding ways to break\n   them nearly his entire life. B
 eing a nerd that likes to dig too far\n   into things spilled over into th
 e real world and he accidentally\n   became a licensed private investigato
 r. Releaser of the occasional\n   tool or writeup on Github\, he wishes he
  had enough time to do all the\n   hacker things and crush griefers in GTA
  Online every day. He received\n   a B.S. in Computer Science from UMBC an
 d an M. Eng. from the Naval\n   Postgraduate School.\n   Twitter: [2]@jayl
 agorio\n\n   Description:\n   How do you go bug hunting in devices you own
  when the manufacturer has\n   slapped some pesky encryption scheme on the
  firmware? Starting from an\n   encrypted blob of bits and getting to exec
 utable code is hard and can\n   be even more frustrating when you already 
 know the bug is there\, you\n   just want to see it! Join me on my expedit
 ion to access the contents\n   of my Zyxel firewall's firmware using passw
 ord and hash cracking\,\n   hardware and software reverse engineering\, an
 d duct taping puzzle\n   pieces together. We'll start with a device and a 
 firmware blob\, flail\n   helplessly at the crypto\, tear apart the hardwa
 re\, reverse engineer\n   the software and emulate the platform\, and fina
 lly identify the\n   decryption routine – ultimately breaking the protec
 tion used by the\n   entire product line to decrypt whatever firmware vers
 ion we want.\n   '\n\n   1. https://defcon.outel.org/consolidated_page.htm
