Corelan Live! by Peter Van Eeckhoutte
The Corelan “BOOTCAMP” is a truly unique opportunity to learn both basic & advanced techniques from an experienced exploit developer, at a conference. During this 3 day course, students will be able to learn all ins and outs about writing reliable exploits for the Win32 platform. The trainer will share his “notes from the field” and various tips & tricks to become more effective at writing exploits.
We believe it is important to start the course by explaining the basics of buffer overflows and exploit writing, but this is most certainly not “your average” entry level course. In fact, this is a true bootcamp and one of the finest and most advanced courses you will find on Win32 stack based exploit development.
This hardcore hands-on course will provide students with solid understanding of current Win32 (stack based) exploitation techniques and memory protection bypass techniques. We make sure the course material is kept updated with current techniques, includes previously undocumented tricks and techniques, and details about research we performed ourselves. Combined with the way the course is built up, this will turn these 2 days into a truly unique experience.
During all of our courses, we don’t just focus on techniques and mechanics, but we also want to make sure you understand why a given technique is used, why something works and why something doesn’t work.
We believe those are just a few arguments that makes this training stand out between other exploit development training offerings. Feel free to check our testimonials page if you want to see real, voluntary, unmodified and uncensored reactions by some of our students.
Finally, we offer you post-training support as well. If you have taken the course and you still have questions afterwards, we will help.
Why take this course?
- Are you interested in the process of turning an advisory into a working exploit?
- Do you want to figure out if a given security patch/hotfix should be applied immediately or not?
- Do you want to learn how to read and understand existing exploits?
- Have you ever found yourself in a position where you have to change an existing exploit but failed to make it work?
- Do you want to write reliable exploits and integrate them into Metasploit?
- Do you want to know how shellcode works?
- Do you have some basic knowledge about win32 exploit development already, and do you want to a good refresher and learn more advanced topics?
- Have you read the Corelan exploit development tutorials, but still want to take the classes to fully understand and master the concepts?
- Do you have other reasons to learn how to write exploits for the Win32 platform?
- Are you willing to suffer and bleed a bit, learn fast and not intimidated by debuggers and assembly instructions?
- ...then this course is exactly what you need!
Pentesters, auditors, network/system administrators, reverse engineers, malware analysts, developers, members of a security department, security enthusiasts, or anyone interested in exploit development.
If you have a strong desire to learn and willing to suffer & bleed, then register for this class.

During the course, students will get the opportunity to work on real vulnerabilities in real applications and use the latest exploitation techniques that work on current Operating Systems.
Make no mistake. Although this course will explain the basics of exploit development, students will need to be able to transition to more complex theory and exercises quickly. The course has a steep learning curve and will require your full attention and focus.
The “Course Contents” on this page is subject to change without prior notice & can be updated between the moment of registration and the actual course. We will try to cover as much as we can from the “Course Contents”, based on the overall ability to absorb knowledge and time needed to complete the exercises, but Corelan GCV cannot ever guarantee that we will be able to cover everything.
Knowledge & Attitude Prerequisites
- be able to read simple C code and simple scripts
- be familiar with writing basic scripts using python/ruby/…
- be ready to dive into a debugger and read asm for hours and hours and hours
- be ready to think out of the box and have a strong desire to learn
- be fluent with managing Windows / Linux operating system and with using vmware workstation/virtualbox
- be familiar with using Metasploit
- No prior knowledge of assembly is required, but it will certainly help if you have some basic knowledge
Technical Prerequisites Unless specified otherwise, students are required to bring the following :
- A laptop (no netbook) with vmware workstation/virtualbox and enough processing power and RAM (we recommend 4Gb of RAM) to run up to 2 virtual machines at the same time. Make sure your laptop has a screen size of at least 15″. The use of a 64bit processor and a 64bit operating system on the laptop will make the exercises more realistic.
- Virtual machines installed, all English versions, (including guest addition tools):
- a 32bit version of Windows XP SP3 Professional, with Internet Explorer 8
- a 64bit version of Windows 7 SP1 with Internet Explorer 9 (32bit version works too) Trial versions are fine. Just make sure the OS won’t expire during the training
- Kali Linux with an up-to-date “git”version of Metasploit:
- mkdir /pentest
- mkdir /pentest/exploits
- cd /pentest/exploits
- git clone git://github.com/rapid7/metasploit-framework.git
- Make sure all 3 virtual machines are configured in an VM internal network, and have full IP access to each other. Disable all firewalls.
- Make sure you know how to change the network configuration to (temporarily) give the VM’s access to the internet (via NAT)
- Make sure all 3 virtual machines are based on ENGLISH versions of the Operating System.
- Make sure you can transfer files from your host machine to all 3 Guest (virtual) machines.
Note : you will receive the exact installation instructions after registration, so don’t start installling the VMs yet.
All required tools and applications will be provided during the training or will be downloaded from the internet during the training.
You must have full administrator access to all machines. You must be able to install and remove software, and you must be able to disable and/or remove firewall/antivirus when necessary.
Peter Van Eeckhoutte is the founder of Corelan Team and the author of the well-known tutorials on Win32 Exploit Development Training, available at https://www.corelan.be. The team gathers a group of IT Security enthusiasts and researchers from around the world, who all share common interests : doing research, gather & share knowledge, and perform responsible/coordination disclosure. Above all, the team is well known for their ethics and their dedication to helping other people in the community. Together with the team, he has developed and published numerous tools that will assist pentesters and exploit developers, and published whitepapers/video’s on a wide range of IT Security related topics (pentesting tools, (malware) reverse engineering, etc). The team also moderates a forum that provides a platform for people who want to talk about exploit development, and operates an IRC channel (freenode, channel #corelan)
Peter has been an active member of the IT Security community for more than 10 years and has been working on exploit development since 2006.
He presented at various international security conferences (Athcon, Hack In Paris, DerbyCon, ISSA Belgium) and delivered the Corelan Live Win32 Exploit Development Bootcamp at numerous places around the globe. He trained security enthusiasts & professionals from private companies, government agencies and military.
