Anti-Debug Time Plugin for OllyDbg V.2 General Information Modern computer programs are more complex in writing and more difficult for reversing. Serious programs have various means of protection against debugging. It prevents application reversing. There are a number of various approaches, like Debug Blocker, Nanomites, others. Measuring time to identify that an application is being debugged becomes the widespread practice lately. The OllyDbg has the «HideOD» and «Hide Debugger» anti-debug plugins, which have no possibility to hide actual time. This causes difficulties in application reversing. Let’s consider the system of debugger identification. The debuggers are ca…

Hello. I'm trying to use VirtualQuery to scan for manually mapped / loaded without LoadLibrary DLL pages inside of a process. I'm scanning between the maximum and minimum application addresses from GetSystemInfo, and increment the current address passed into VirtualQuery each loop itteration by RegionSize from MEMORY_BASIC_INFORMATION; My question is, what checks should I put on MBI allocationbase, state, protect, type etc. in order to find manually mapped pages of the DLL in the process. In the end I want to be able to dump the pages of the .text, .rdata, .data, etc. segments from the process for further analysis.

I think I've not seen a kernel-mode code. What is the difference between a user-mode program and kernel-mode program at code level? int main(){ puts("HW"); } It's simple user-mode code/program, is there something similar for kernel-mode code/program? What is a difference between writing user-mode and kernel-mode program? Are there same APIs, etc.

Hi again, does anyone know any function/s to split a text file (any text of notepad etc) into single lines by CRLF? Example: I have simple textfile which has 10 lines (each line with return at the end / CRLF) and now I read the file into buffer via ReadFile API and now I got the whole text in buffer and now I need to check manually for CRLF at the end or not if not present etc.So is there any simple function/s etc I could use to get a entire line by line back?Maybe there is anything I could use and dont know yet. Thank you
