New AntiDebugging Timer Techniques
Almost everyone involved in the reverse engineering knows about the timer checks used for antidebugging. Generally functions such as GetTickCount or KeTickCount are used to detect and prevent any debugging attempts. Recently in the Hackers Reversing Challenge 2007, one of the less known timer checks have been used which makes use of functions QueryPerformanceFrequency & […]

F-Secure has announced new Reverse Engineering Challenge for the summer assembly event. The challenge is very interesting and neither easy nor difficult. It has 3 levels, at each level you have to find out email address which will take you to the next level. The challenge was announced a day back and already 18 people […]
Detecting & Defeating the Debuggers
Debuggers are the main tool used in reverse engineering. It is used by serial crackers to break the software protection or to uncover the algorithm used in the proprietary applications. On the other hand it is also used by researchers to analyze the malwares. Detecting the presence of debuggers is an important step in this […]
ProcHeapViewer : Faster way to enumerate...
ProcHeapViewer is a fast heap enumeration tool which uses better technique than normal Windows heap API functions. Its very useful tool for anyone involved in analyzing process heaps. Vulnerability researchers can find it useful while working on heap related vulnerabilities. Traditional Windows heap enumeration functions are slower and takes lot of time while traversing large […]
ReactOS : Source for Windows OS
ReactOS® is an advanced free open source operating system providing a ground-up implementation of a Microsoft Windows® XP compatible operating system. ReactOS is currently in its alpha stage and there is long way to go.Though its not exact replica of Windows XP, its near match. Moreover all function names are same as that of Windows. […]
