Application Security: For Hackers and Developers

Crucial Security

There are four technical skills required by security researchers, software quality assurance engineers, or developers concerned about security: Source code auditing, fuzzing, reverse engineering, and exploitation. All these skills and more are covered in a new and exciting Crucial Security course developed by senior security researcher Jared DeMott. C/C++ code has been plagued by security errors resulting from memory corruption for a long time. Problematic code is discussed and searched for in lectures and labs. Web auditing is covered using WebGoat. Fuzzing is a topic book author DeMott knows about well. Mutation file fuzzing and framework definition construction (Sulley and Peach) are just some of the lecture and lab topics. When it comes to reversing C/C++ (Java and others are briefly discussed) IDA pro is the tool of choice. Deep usage of this tool is covered in lecture and lab. Exploitation discussions and labs are the final component. You’ll enjoy exploiting BSD local programs to Vista browsers using the latest techniques.

Reverse Engineering

Students focus on learning to reverse compiled software written in C and C++, though half-compiled code is mentioned as well. The IDA pro tool is taught and used throughout. Calling conventions, C to assembly, indentifying and creating structures, RTTI reconstruction are covered. Students will also use IDA's more advanced features such as flirt/flare, scripting, and plug-in creation.

Source Code Auditing

Understanding how and when to audit source code is key for both developers and hackers. Students learn to zero in on the important components of each language. Automated tools are mentioned, but auditing source manually is the focus, since verifying results is a required skill even when using the most advanced tools. Spotting and fixing bugs is the focus.


Fuzzing is a runtime method for weeding out bugs in software, with a growing footprint within security companies and research communities. Techniques such as dumb file fuzzing, all the way up to intelligent network protocol fuzzing will be covered. Students will write and use various fuzzers to find bugs.


Students will walk out of this class knowing how to find and exploit bugs in software. This is useful to both developers and hackers. The exploit component will teach each common bug type including: stack overflows, function pointer overwrites, heap overflows, off-by-ones, FSEs, return to libc, integer errors, uninitialized variable attacks, heap spraying, and more. Shellcode creation/pitfalls and other tips and tricks will all be rolled into the exciting, final component.


  • College Degree in a computer related disciple or equivalent work experience
  • Read DeMott's recently released "Introduction to Application Security" if possible.

By the end of this course, you will be able to: research and develop an exploit from scratch by auditing code or fuzzing an application, reverse engineering the issue, and developing a exploit for the vulnerability you discovered. This knowledge will help developers produce better code, and will help security researchers or malware analysts in their daily tasks

College Degree in a computer related disciple or equivalent work experience

Doing this class in two days is pretty intense, trainees are encouraged to brush up on C/C++, *nix commands/file structure, Perl, Python, Assembler, basic use of Visual Studio


Jared DeMott is a Senior Security Researcher for the Crucial Security programs area of Harris Corporation. Crucial provides state-of-the-art technical engineering and security services to the most elite branches of the Federal Government’s law enforcement and intelligence communities, engineering solutions to meet their demanding requirements. Mr. DeMott previously worked for the NSA and currently teaches computer security at university and professionally. He has spoken at security conferences such as Black Hat, Defcon, ToorCon, and Shakacon. This background provides an ideal blend of skills for teaching cutting edge security material, in a fun and instructive manner.
