Hello all, So I've been bashing my head against a wall for a few hours on this issue and I'm not entirely sure what the problem is. When I step debug the application, it's breaking on this: CALL lstrcpyA The Error seems to be changing each time, first time it was array out of bounds, second time it was erroring with "Privileged instruction" I'm just not entirely sure what the issue is. Anyhow, here's the source. Can anyone possibly lend a helping hand here? Thanks ! #include <windows.h> #include <iostream> #include <string>using namespace std;void MyFunction(long int one); char alpha[] = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ"; char one[] = "STD"; char …

Hi, I'm analyzing a licensing process of a program and I came across those functions (bellow) I found that it is using SHA-1, zlib decompression, upx for internal module, and not sure about RSA zlib and upx functions I've already recognize them, but SHA-1 and RSA (?) are still under question. Here are a part of function before the data is actually decrypted. The Functie_RoR_cu_shl8 looks like SHA-1, and the cycle is feeding the digest (?). I need to know if I understood this function correctly and if somebody recognize the Spider_Unknown_Function? If you can help me understand better this peace of code. Thanks. All those inline algorithms looks like Crypto++ library or Bo…

Change class name onmouseover
by kuma.lk- 0 replies
- 3.2k views
I'm trying to find a way to use Javascript to find elements with a specific class, dynamically change the class onmouseover, and return the element to its original class onmouseout. Obviously there are a ton of scripts out there that have this kind of functionality, but I need something that I can put into an external javascript, without having to add anything to the markup. I've tried to hack something out, but unfortunately don't know enough about javascript to make it work. Any ideas? Thanks, _______________________________________________________________________________

PEDiminisher unpacker

- 7.5k views
Hello friends, i'm proud to bring you my unpacker for PEDiminisher v0.1 from Teraphy. Why do i say "Complete decryptor" ? - PeDiminisher Unpacker (Direct approch) from DESPERATE is failing with original PED, my unpacker is working. - Generic unpackers and PeDiminisher Unpacker (Debug approach) from DESPERATE are working with PED, but you can't remove "extra" sections from PED if "Encrypt resources" and "Exclude Icons" were checked. In default, PED creates a ".teraphy" unpacking section in packed file. In case "Encrypt resources" and "Exclude Icons" were checked, PED creates an extra section named ".icon", where it duplicates icon contents from resource to this new ".icon…

DeviceIoControl IOCTL codes.

- 13.4k views
Delphi didn't seem to have these predefined, so I had to calculate it myself. Since it can be pretty tough finding the right values (even with Google) I thought I'd just calculate them all and share the list with you. They are for use with the DeviceIoControl() API. I have found the code used to calculate the values on internet and only had to find the right parameter values, thus not too much credit should go to me. This function being: function CTL_CODE(DeviceType, FunctionNo, Method, Access: Integer): Integer; begin Result := (DeviceType shl 16) or (Access shl 14) or (FunctionNo shl 2) or (Method); end; As for Method and Access, these are the values used for them: …
