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.
