Architecture 1001: x86-64 Assembly


OpenSecurityTraining2

About This Course

Intel processors have been a major force in personal computing for more than 30 years. An understanding of low level computing mechanisms used in Intel chips as taught in this course serves as a foundation upon which to better understand other hardware, as well as many technical specialties such as reverse engineering, compiler design, operating system design, code optimization, and vulnerability exploitation.

This class serves as a foundation for the follow on "Architecture 2001: x86-64 OS Internals" class. It teaches the basic concepts and describes the hardware that assembly code deals with. It also goes over many of the most common assembly instructions. Although x86 has hundreds of special purpose instructions, students will be shown it is possible to read most programs by knowing only around 20-30 instructions and their variations.

Requirements

You must be comfortable with C programming.

If you need to learn C, we recommend Learn-C.org, and Dartmouth's 'C Programming with Linux' edX class.

Frequently Asked Questions

What learning paths is this class used in?

Exploits, Reverse Engineering, Malware Analysis, and System Security

Does the instructor teach this class in person?

Yes, but only occasionally. Xeno's preferred in-person delivery method is a hybrid structure where we get everyone in the same room, and students proceed through the class at their own pace by watching videos. Xeno is then available in person and chat to answer questions immediately when they occur. He only does live-lecture classes for companies that have sponsored OST2, if they insist that they want this anachronistic and arguably suboptimal delivery method.

To be or not to be?

That is the question...

Xeno founded OpenSecurityTraining in 2011 to share his and others' trainings more widely. He relaunched OST2 in 2021.

Xeno's from Minnesota and has a BS in CS from UMN. He received a MS in computer security from Carnegie Mellon through the National Science Foundation "CyberCorps Scholarship for Service". But the US government didn't really yet know what to do with "cyber" people in 2007; so he ended up going to work for a Federally Funded Research and Development Center - MITRE. Xeno worked exclusively on internal-funded research projects, first as a participant and later as a leader on Windows kernel malware detection and trusted computing projects. Towards the end, other cool researchers inspired him to dig into BIOS and firmware level threats.

Xeno left MITRE to start an independent consultancy, LegbaCore, with Corey Kallenberg in 2015. Less than a year later, under mysterious circumstances that he's legally prevented from stating, he started working for Apple. While at Apple he helped get SecureBoot on Macs with the addition of the T2 chip. He also led the SecureBoot design and implementation project for the ARM-based M1 Macs. But between those big, visible, multi-year, projects, he was silently improving the security of a bunch of the 3rd party peripheral processors' hardware and firmware. He liked working at Apple because he had a bully pulpit where he could force 3rd parties to do the right thing or lose their business. But he likes OST better, so he left in 2020 to work on this full time.

Xeno has a touch of the illness known as being a "collector" (it's not quite to the level of being a "hoarder", so he can't get on TV for it or anything...) Consequently he has presented at IEEE S&P, ACM CCS, BlackHat USA/EUR, Defcon, CanSecWest, PacSec, Hack in the Box KUL/AMS/GSEC, Microsoft BlueHat, Shmoocon, Hack.lu, NoSuchCon, SummerCon, RSA, ToorCon, DeepSec, VirusBulletin, MIRCon, AusCERT, Trusted Infrastructure Workshop, NIST NICE Workshop, and the DOD Information Assurance Symposium. And yet he still says "MORE!"
