Rakan El-Khalil is currently on sabbatical in France. He is a recent MS CS graduate from Columbia University. While he was there he worked on a variety of projects at the CS Research Lab, such as an IDS that uses machine-learned models to detect network threats, and a syscall based permission system on OpenBSD [predating systrace]. He was also responsible for the short-lived official KaZaA Linux client `kza'. Currently he is involved with The Bastard, a powerful linux disassembler, and has been researching steganography and information hiding in machine code.
