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
- 3k 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. Post your thoughts, please!

Call c++ member function through asm
by urbanyoung- 2 replies
- 3.6k views
Hey, I'm trying to call a c++ class member function through asm. I believe the this param (class id) is passed using ECX in the function call, getting this is no problem. However, when I call the function (with the class id in ECX) the function doesn't crash like before, but it returns incorrect data. I was wondering if anything else needs to be passed to the function or if ECX is infact the class id used to associate data with the caller. Any tips would be appreciated.

Hi, I am just asking how to read text that is multilined, in a text box, into a formatted memory buffer. This is needed because the required function that needs the text, expects it to be formatted. And so, the app fails because the text is not formatted properly (with newlines etc). The language the project is written in is C++, with zero MFC or .NET. Any assistance at all would be appreciated. EDIT: Worked it out. For some odd reason, the edit control's contents (which are on tabs) are not read...

[Delphi] Resource section help
by steve10120- 0 replies
- 3k views
Hi, I've got another problem. I'm trying to read the read and parse data in the resource section, after reading some articles I've got a pretty good idea about what needs to be done. But, I'm stuck on one little thing, which none of the articles seem to cover. The problem is with the IMAGE_RESOURCE_DIRECTORY_ENTRY values, the Name value seems correct(checked with Index refs), but the OffsetToData value is wrong, or at least the value in the field is way way above even the filesize. Is there something I need to do to the OffsetToData to get the right offset of the IMAGE_RESOURCE_DATA_ENTRY? var dwOffset: DWORD; bFile: TByteArray; IDH: TImageDosHeader; INH: TImageN…
