Dates: 20th to 21th Sept 2016
This course introduces and explores attacks on several different relatively accessible interfaces on x86 systems. Attendees will get hands-on experience implementing and deploying a number of low-cost hardware devices to enable access, privilege, and deception which is in some cases imperceptible from software.
The course has several modules. Each begins with an architectural overview of an interface, and follows with a series of labs for hands-on practice understanding, observing, interacting with, and exploiting the interface, finishing with either potentially exploitable crashes or directly to root shells.
Depending on allotted time, topic interest, and class pace, not all topics will be covered completely, but all materials are included for reference and individual practice.
