| IDA Plug-In Writing in C/C++
| IDA Plug-In Writing in C/C++
After spending a lot of time going through the header files in
the IDA SDK as well as looking at the source to other people’s
plug-ins, I figured there should be an easier way to get started
with writing IDA plug-ins. Although the header file
commentary is amazingly thorough, I found it a little difficult
navigating and finding things when I needed them without a
lot of searching and trial-and-error. I thought that I'd write
this tutorial to try and help those getting started as well ...

| Cryptography in Data Compression
| Cryptography in Data Compression
This paper describes cryptographic methods for concealing
information during data compression processes. These include novel
approaches of adding pseudo random shuffles into the processes of
dictionary coding (Lampel-Ziv compression), arithmetic coding, and
Huffman coding. An immediate application of using these methods to
provide multimedia security is proposed.

| Guide on How to Play with Processes Memory,
| Guide on How to Play with Processes Memory,
This tutorial aim is to do a whole flight over loaders, memory patching and how to build
them. Told this you might think that there’s nothing new in this, because there are several
excellent tutorials (not that many anyway) already around, which already cover this
argument, but the real final target of this tutorial is to teach how to write an “Oraculum”,
and to write an Oraculum is impossible without first of all understanding all the things about
loaders, processes and memory patching of ...

| Scan of the Month 33
| Scan of the Month 33
The purpose of this "tutorial" is to provide an in-depth analysis for the executable provided in the present challenge [1]. This analysis will be obtained through a complete reverse engineering of the target, bypassing all "tricks" which have been adopted to make harder the job. We will document the procedures, tools and methods used for this purpose.

| Low Cost Embedded x86 Teaching Tool
| Low Cost Embedded x86 Teaching Tool
The wide availability of personal computer based on the x86 architecture that conform to the PCI specification
version 2.1 and Plug and Play BIOS specification version 1.0A or higher, along with the existence of free open
source software development tools for this architecture, provides an opportunity to create a low cost embedded
system teaching tool based on it. In this paper we will explain one of the implementation of this idea by
exploiting the so called "Bootstrap Entry Vector&q... Read More >> |

| Advanced Award BIOS v4.51PG Hacking
This tutorial is intended for people who already done some award bios modification before, and already knows
the core component of award bios. In case you haven't done it or haven't know anything yet, you can read
somewhere else. I have provided links to bios related website in the front page of this website and also I've made
tutorial called Preliminary Bios Modification Guide and Mainboard Bios Components. As the title said, what I'm
going to explain here only apply exact... Read More >> |

| Anti Reverse Engineering Uncovered
| Anti Reverse Engineering Uncovered
Rather than doing another complete analysis of the binary, i will rather present the techniques i have used in the challenge, and how i have implemented them. The Scan of the Month 33 was released by the Honeynet Project in November 2004. I invite everyone to read the excellent submissions we received this month once they have read my paper. I am presenting the binary from the protection author point of view, while they presented it from the analyst point of view. You will learn the methods and ...

| VX Reversing III – Yellow Fever (Griyo 29a)
| VX Reversing III – Yellow Fever (Griyo 29a)
This article provides an in-depth analysis of the I-Worm "win32.YellowFever", by "Griyo29A". This is a proof
of concept virus, meaning it has very sophisticated features which are very hard to find in the wild. Our analysis
includes: a step-by-step guide to debug it and the construction of a bait file, which we use to run it under a
controlled environment. Since the virus has not been spread there is no similar description published by the
Anti-Virus companies.
