Inside Code Virtualizer
Inside Code Virtualizer Inside Code Virtualizer
This article aim to explain how Code Virtualizer works. During the last month, I spent all my free time analysing the Code Virtualizer Demo 1.0.1.0 unpacked by softworm. Fortunately, I finished my analysis and I can say that this is the best software I have seen before. Not best in the meaning of protection, but in the meaning of organization. This was the most pleasing software I have analysed. Three important things to notice are that the description and explanation of the code...

Reverse engineering techniques to find security bugs: A case study of the ANI
Reverse engineering techniques to find security bugs: A case study of the ANI
Alex Sotirov is a vulnerability engineer at determina. He will discuss some latest techniques in reverse engineering software to find vulnerabilities. Particularly, he'll discuss his technique that lead him to find the ANI bug (a critical new bug in WinXP and Vista). Alex will describe the tools he uses for reverse engineering and show how he reverse engineered ANI Bug. He will continue to discussed Windows security mechanisms (ASLR, /GS) and describe how ANI exploit bypasses the...

Mammon_'s Tales to his Grandson - Linux on the Half-ELF
Mammon_ Mammon_'s Tales to his Grandson - Linux on the Half-ELF
It would be nice to start this paper off with a grandiose statement sweeping across the years, declaring that in these times of hostile code, network intrusions, vendor [un]accountability, and fierce competition, that reverse engineering skills are needed more than ever. This is simply not the case, however; "reverse engineering" as a process may have become more widely used in the software industry, but it has been the foundation of the technical fields -- electronics, engineer...

Why write your own packer when there are so many existing ones to choose from? Well, aside from making your executables smaller, packing is a good way to quickly and easily obfuscate your work. Existing well-know packers either have an explicit 'unpack' function, or there are readily available procdump scripts for generating an unpacked version....
