Peter is exceptional. His Heap training course is simply outstanding. It stretched my brain to its limits and fundamentally changed how I think about heap exploitation. Immediately after the training, I was able to experiment with, observe, and understand concepts in modern AI-assisted kernel heap exploitation that I could not have imagined before. The course itself is not about AI-assisted techniques or kernel heap exploitation, but the way Peter teaches you to think makes the transition to those areas remarkably natural. What makes this course special is that Peter teaches you how to think, not just how to solve a particular heap exploitation problem. The principles and mindset you develop transfer to entirely new challenges and research. If you’re serious about heap exploitation, I can’t recommend this course enough. Take it, and enjoy having your brain melted in the process.
What stood out most about Peter’s teaching style was the focus on strategy and reasoning rather than just isolated examples. Instead of memorizing techniques, the class emphasized understanding the mindset behind each step in modern heap exploitation.
And that’s what made this experience so impactful!
At the end of day 4, heavily sleep deprived, there was pure silence in the room. We were still trying to comprehend what we had just gone through.
Peter shows you the way, but you need to walk it on your own.
This is by far my proudest certificate to date, but it does not mark an ending. Rather the start of a huge new chapter!
Coming into this course I expected to be taught a methodology for exploitation of stack and heap vulnerabilities in Windows. Not only did Peter teach this to a high degree, he also explained how the technology worked in an engaging and detailed manner, enabling the class to not just understand how to exploit a vulnerability, but why it works and how we can enable our own creativity to solve problems without following a “tutorial”. I firmly believe this type of teaching is what students need to stand out in such a competitive industry.
The Corelan Heap Master Class is exactly that—a master class. Over four days, we went from the basics to the absolute depths of heap internals. I won’t lie; it was tough. The concepts are deep, and the pace is intense (and yes, the corrective push-ups are real!). But the feeling of understanding these complex mechanisms by the end of Day 4 is unmatched. Peter has a unique gift for breaking down the most difficult concepts, and the Redfacers team organized a seamless experience. It was a fruitful four days that pushed me physically and mentally. I’m already looking forward to the next one.
Attending the Heap Masterclass was hands down one of the best decisions I’ve made for advancing my binary exploitation skills. Peter’s crystal-clear explanations and real world examples drawn from years of his own rigorous, dedicated work helped me in conceptualizing how memory was being allocated and free’d.
With better understanding, it allowed me to perform heap techniques with better precision. I walked away knowing the ‘why’ in addition to the ‘how’. it is definitely worth every minute and penny.
I had limited knowledge about the Windows heap prior to the class and was hoping to finish the training with a better understanding of it. I walked away not just with much more confidence on the topic, I gained so much more than that. His sharing of powerful research methodologies based on insights developed from years of dedicated research completely exceeded my prior expectations of the class. Not to mention, Peter has a fantastic way of breaking down complex concepts into an easier to understand fashion that makes things much less intimidating.
Thank you Peter! This was an amazing experience.
I recently completed the four-day Corelan Heap Masterclass, and it exceeded every expectation. The course offers a deep, structured, and highly practical look into heap internals and exploitation techniques. What stood out most was the clarity of the explanations, where complex concepts that normally take a long time to fully understand were broken down into logical, digestible steps without ever sacrificing technical depth. Peter’s teaching style combines expertise, patience, and the ability to make intensely technical material engaging and accessible. This training pushed me, challenged me, and ultimately gave me a far stronger understanding of heap behavior and exploitation. It’s an intense experience, but absolutely worth it for anyone serious about advancing their skills.
Peter is an amazing teacher on what is truly a mind bending class on Windows heap exploitation. I started this class with almost no prior knowledge about the Windows Heap and by the end of the class not only did we see in detail the behavior of Heap, but also how can you apply different approaches and methodologies from the best. Really great content, tons of exercises exposed through incremental steps to such a dense topic. In my opinion, a truly unmatched class on the topic! I’ve had the Stack class as well, and at the time it was the best security related class I’ve ever attended. Heap built on that and was an even bigger eye opener, being the best class I’ve ever attended!
I really enjoyed and learned a lot of things during the Heap masterclass. I really liked the fact that we started by learning all the technical concepts before diving into the vulnerabilities. The class is really intense in term of content, but Peter managed to summarize 15+ years of research in 4 days, so the class is really worth it. Also, Peter is a great teacher and was able to answer all our questions.
I had the chance to take the Corelan Heap Masterclass. It was a great course that allow to demystify heap exploitation. Peter explained really well the key concepts and the methodology needed and show practical use cases that can be applied to real life situations. The course was really dense but Peter successfully make it fun and easy to follow. I highly recommend this training.
