With stories of "BadBIOS" infecting PCs simply by connecting a malicious USB flash drive to a PC, it's time we learned about flash drives and their controllers. Consumer USB flash drives are cheap, growing in capacity and shrinking in physical size. There are only around 15 prominent controller chip manufacturers whom you have never heard of, but OEM for all the popular and respected "name brands" on the market. These flash controllers have capabilities that aren't mentioned on product packaging, and can be enabled with programming you will learn during this presentation. These flash controllers can be *reprogrammed entirely* via software to do whatever you want.
Turn an old flash drive into an emulated CDROM or a CDROM + flash drive. Update the controller's firmware, disassemble it, etc. This talk will touch on the various controller manufacturers, features, and show you how to leverage them for yourself. Why spend $100 on an old SanDisk[tm] U3 Cruiser when you can spend $4 for the same features?
