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 by Xeno Kovah 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.



25% of the time will be spent bootstrapping knowledge of fully OS-independent aspects of Intel architecture. 50% will be spent learning Windows tools and analysis of simple programs. The final 25% of time will be spent learning Linux tools for analysis.

This class serves as a foundation for the follow on Intermediate level x86 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.



The instructor-led lab work will include:


* Stepping through a small program and watching the changes to the stack at each instruction (push, pop, call, ret (return), mov)

* Stepping through a slightly more complicated program (adds lea(load effective address), add, sub)

* Understanding the correspondence between C and assembly control transfer mechanisms (e.g. goto in C == jmp in ams)

* Understanding conditional control flow and how loops are translated from C to asm(conditional jumps, jge(jump greater than or equal), jle(jump less than or equal), ja(jump above), cmp (compare), test, etc)

* Boolean logic (and, or, xor, not)

* Logical and Arithmetic bit shift instructions and the cases where each would be used (shl (logical shift left), shr (logical shift right), sal (arithmetic shift left), sar(arithmetic shift right))

* Signed and unsigned multiplication and division

* Special one instruction loops and how C functions like memset or memcpy can be implemented in one instruction plus setup (rep stos (repeat store to string), rep mov (repeat mov)

* Misc instructions like leave and nop (no operation)

* Running examples in the Visual Studio debugger on Windows and the Gnu Debugger (GDB) on Linux
* The famous "binary bomb" lab from the Carnegie Mellon University computer architecture class, which requires the student to do basic reverse engineering to progress through the different phases of the bomb giving the correct input to avoid it "blowing up". This will be an independent activity.



Knowledge of this material is a prerequisite for future classes such as Intermediate x86 (playlist:http://bit.ly/HIaD4O) , Rootkits(playlist:http://bit.ly/HLkPVG), Exploits, and Introduction to Reverse Engineering.

  Your Videos on Assembly Language Programming are Very Excellent ^ other Series video on your website were simply Awesome.
  
  Thanks a lot ...really once again Thank a lot....Open Security Training Team & Vivek for providing these videos....
  
  And there is no enough language to describe my happiness towards this series & others on Open Security training ....

  Thank you so very much! Like d3crypt0R said, this is really, really awesome! Im lost for words...
  
  I feel like Im in heaven. Seriously. This is as good as it gets. Thanks a ton to both OpenSecurityTraining and of course, the man himself, Vivek. =))

  lol... It's incredible how much knowledge i absorbed from these video tutorials, starting from this one. I really dunno how i can thank you! So useful, and straight to the point.. Your tutorials have resurrected my understanding of assembly to another level, thank you.

  You can thank us by telling other people about the site, so more people can learn, and more people can teach. Just like open source code, many people can be users, but it's harder to find contributors (which here could mean people who take the material and teach in their own venue, or people who already have classes >= 1 day and contribute their material.)
  
  Thanks
  
  Xeno
