This course will cover USB in detail with an emphasis on understanding USB Mass Storage devices (also known as flash drives or thumb drives).By the end of this course students will know how to sniff USB traffic using open source tools, be able to write-block USB mass storage devices using software and microcontroller-based hardware, be able to impersonate other USB devices, and understand how to make forensic duplicates of USB mass storage devices. Along the way students will also learn how to use microcontrollers and Udev rules.
