Question about Windows memory architecture
by M4RCKUS- 2 replies
- 3.2k views
I'm very confused about one thing in Windows memory architecture. Thought someone here could help me out. The Virtual Address space (numbering) is unique to every process, right? I.E. application "A" can have some data structure at address 0x12345678, while another completely different application "B" can have completely different data structure at same address 0x12345678. Correct me if this is wrong. Now, assuming this, why is that virtual address space is split into partitions like from 0x00010000 to 0x7FFEFFFF for user mode applications and from 0x80000000 to 0xFFFFFFFF for kernel-mode apps. Why can't user-mode app take the "higher" part of address space if the space n…

Hi guys, this is my first attempt to use RSA in a .NET app. I looked for a solution for hours but I did not understand how to use RSACryptoServiceProvider to import my chosen keys. // Imposta parametri RSAParameters rsaParams = new RSAParameters(); rsaParams.Modulus = myData.getN; rsaParams.Exponent = myData.getExponent; // Istanzia il crypter CspParameters providerParam = new CspParameters(1, "Microsoft Enhanced Cryptographic Provider"); RSACryptoServiceProvider myRSA = new RSACryptoServiceProvider(48, providerParam); myRSA.ImportParameters(rsaParams); // ALWAYS BA…

PNG As Window/Region?
by Hyperlisk- 3 replies
- 3.7k views
Hi, I was wondering if anyone has any code they could share that demonstrates how to use a png image as a window. I have no idea where to start... I assume Either GDI+ or pnglib, but that's about it... But yeah... If anyone has anything they can share, I would be delighted to look at it. Hopefully in C/C++ or MASM, but I'm sure anything will be fine if I can adapt it. Thanks, Hyperlisk

Hi i seem to be having a problem with my LoadBitmapW hook, im using Detour 2.1 Im trying to hook SPIDER.EXE Windows XP version of the game, SPIDER.EXE resource has Numeric and String resources bitmaps for ids example 108,106, "FELT", "CARDBACK", "CARD1" etc etc FELT, CARDBACK will pass just fine in the LPCWSTR lpBitmapName, but when spider.exe resource has 2 images as Numbers resource bitmap id 108, 106.. the debugger tells me bad ptr 0x00006c (lpBitmapName) etc.. which is the 108 resource id for the bitmap HBITMAP __stdcall Mine_LoadBitmapW(HINSTANCE hInstance, LPCWSTR lpBitmapName) { HBITMAP hBitmap = NULL; TCHAR tszModuleName[MAX_PATH] = {0}; GetModuleBaseName(GetC…

Is there a plugin that allows to translate basic asm code from olly to c++/c# commands? I'm talking really the most basic commands like: SHL EAX,0A --> EAX = EAX << 0x0A OR EAX, ESI --> EAX = EAX | ESI AND EAX, ESI -> EAX = EAX & ESI XOR EAX,EBX --> EAX = EAX ^ EBX MOV EAX, EDX -> EAX = EDX etc... Please don't tell me to use inline asm because I'm programming in C#, which apparently does not support inline asm. And at the same time please dont tell me to use C++ as i already coded a lot of code for this keygen I'm working on and I'm not going to translate the code to c++.

Irregular shaped applications
by HellSpider- 6 replies
- 5.7k views
Hi. I've started to learn coding with MASM and I'm coding a program with an irregular shape atm. The problem is that my region and the bitmap that should get placed on the region are not one the same place. The bitmap is like one centimeter below the region. So what I'm asking is for a solution to fix this. Here is a picture of the mismatch of the region and the bitmap: Now my code looks like this: ... invoke LoadIcon, hInstance, 2001 invoke SendMessage, edi, WM_SETICON,TRUE,eax invoke SetWindowText, edi, offset lpAppName invoke SetWindowPos,edi,HWND_TOPMOST,0,0,0,0,SWP_NOACTIVATE + SWP_NOMOVE + SWP_NOSIZE invoke LoadBitmap, hInstance, 2003 invoke CreatePatternBru…

Coding our own little packer
by azfk- 1 reply
- 3k views
I'm just curious about this because if we were to code our own packers, it would be a great learning experience in programming, improving our thinking skills (doing anything really), and understand how to unpack better, I've made my own little project, I'm just going to generate a few keys and encrypt blocks of data accordingly, but I'm still stuck on how the unpacking stub works, do I code it manually beforehand and just write the code over what I'm protecting? If so that seems godawful for more complex packers like execryptor and themida so I think thats impractical, or is it an engine? If so... I would need to code my own engine? any comments? thoughts, ideas, will be…

Ollydbg text assembler (concept)
by Guest Dreamer9210- 6 replies
- 3.5k views
Hello! I'm using OllyDbg quite often, and sometimes I use it to add/edit functionality to existing binary applications. It's very convenient to see the changes in real time, being able to insert breakpoints while writing/editing the code. But the main problem, in my opinion, is that it's difficult to maintain already written code - if I have to insert or remove commands, I have to manually fix calls/jumps. That's why I wanted to write a plugin to fix the situation, but I am not experienced in writing OllyDbg plugins, and I don't have much time for it, so I want to share the concept with you: Click here It's similar to the known Code Ripper plugin, with an extra feat…

Ollydbg Plugin Plus Masm Source
by What- 15 replies
- 16.1k views
Here is the source for a plugin, I have decided to write a new one from scratch with completely custom code.. Its has fixes for stuff like IsDebuggerPresent, HeapFlags, and shows hooks for stuff like ZwQueryProcessInformation. Show how to apply fixes to ollydbg itself, remove ep breakpoint and break on tls. Hope this helps someone. Originally I used a thread on restart of plugin but it was kinda annoying, so I hooked ollydbg later on where all the fixes would work right, took forever to find a good spot.

Sometime last year I remember someone asking for an example of anti-odbg in Delphi. Though this is just a simple example code can be modified and updated. Original thread was on unpack.cn sometime ago and this evening while I was checking the board I came across this thread and figured it would be a good opportunity to post it on tuts4you. If you use the code or find it helpful be sure to email this guy and thank him.
