Irregular shaped applications
by HellSpider- 6 replies
- 5.5k 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…

I work in c++ at a project and I can say that if someone change a char array with a debugger my app is hacked. How should I protect that array? I was thinking to have more arrays and if I join them(when I need) to result my array.

Hi guys, This morning (in my time zone ) I wrote a little txt-file explaining the basic approach to redirect imports of an app. This would be especially useful when u write your own protector or something else...

Coding our own little packer
by azfk- 1 reply
- 2.8k 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
- 3.2k 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
- 15.7k 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.

antiodbg src -> Delphi

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. Dont be a JP function IsDebuggerPresent():BOOL; stdcall;external 'kernel32.dll' name 'IsDebuggerPresent'; <-- !patch Kernel32.IsDebuggerPresent SimpleAntiDBG2.zip

Since I don't make nearly enough contributions around here, time to throw down a few of my projects I've posted on other communities __ Anti-debug library, "Siberian Tiger", build 0.900: http://www.sendspace.com/file/lknuyt. ASM files, as well as intrinsics, are used to be compatible with both x86 and x64 platforms. Strings are encrypted as a small layer of protection from reverse engineering. As the library approaches it's final revision, I'll be obfuscating the application a bit more to ensure all checks are able to run, and work a bit more on integrability. __ - Checks all modules entrypoint for being outside module space and the code segment; if size image or …

Hook/Call the same function?
by high6- 2 replies
- 2.8k views
So I have a C++ dll injected into a process and I want to hook/call the same function. Problem is that if I have the hook call the function then it can turn into some nasty recursion. What is the best way to Hook/Call the same function? Some thoughts -Could call the hook's trampoline instead which will cause it to skip over the hook. (Will only work if hooking the start of a function) -Could set a flag that will skip the hook. Not sure how I would do that without it being a giant mess though.

PE-Nightmare v1.3 decryptor

Hello guys... Just after updating Yoda's Decrypter to v1.1, i'm proud to bring you my PE-Nightmare v1.3 decryptor. This crypter is very easy to study, but it has a bad file alignement, causing not working on NT Technology. If you've crypted a proggy that can't be run on NT, just decrypt it with this decrypter and it should work. I have also included source code in masm for those who are interested... See you soon in my next decrypter... Laurent aka BIGBOSS from COPs Any remarks are welcome... CPS!UnPENightmare.zip PENightmare_v13.zip

Hi guys. It's me again, with another kinky weird request from y'allz. Do you happen to know the fastest way to clear all registers? (e-a-c-d-b-x, e-s-d-i) I wrote something like this, keeping in mind I want code to be small: _WIPE proc push 6h pop ecx @loop: push 0 loop @loop pop eax pop ecx pop edx pop ebx pop esi pop edi ret _WIPE endp Pretty much looks like a Delphi function in prolog, lol.
