Summary

Welcome to a deep dive into modern JVM internals and hacking techniques in December 2025. I am currently an active researcher specializing in reverse engineering, OpenJDK contributions, and JVM internals. My latest work, titled "Hijacking the VMs JIT," explores how HotSpot JIT trusts compiled code, offering a potential method to abuse those trust mechanisms. Additionally, I published a blog post on November 8th detailing the challenge of getting JVM instrumentation running without an external agent. I also recently shared an article on October 19th examining the specific workings of the JVM's classloader architecture. While these papers provide a theoretical foundation, they highlight significant challenges for developers seeking low-level control over JVM execution. By understanding these core components, developers can better navigate the complexities of virtual machine management and application development.
