Joachim has been involved in freelance security work, reverse engineering (burneye), low-level coding, exploit development, codebreaking and some kernel module experiments on windows and linux operating systems.

In his presentation on feedback fuzzing, a feedback loop between the internal state and jump decisions of the cpu - as given by the emulator Bochs - and the fuzzer will be investigated as a means of efficiently enumerating all possible execution paths potentially leading to exploitable bugs in IA-32 programs and/or the underlying operating system.

Joanna Rutkowska
Joanna Rutkowska has been involved in computer security research for several years. She has been fascinated by the internals of operating systems since she was in primary school and started learning x86 assembler on MS-DOS. Soon after she switched to Linux world, got involved with some system and kernel programming, focusing on exploit development for both Linux and Windows x86 systems.

A couple of years ago she has gotten very interested in stealth technology as used by malware and attackers to hide their malicious actions after a successful break-in. This includes various types of rootkits, network backdoors and covert channels. She now focuses on both detecting this kind of activity and on developing and testing new offensive techniques.

She currently works as a security researcher for COSEINC, a Singapore based IT security company.
