- 6.3k views
What is PortEx?PortEx is a library aimed at Java developers and reverse engineers. It enables you analyse Portable Executable files (e.g. EXE, DLL files) and has a special focus on malware analysis. In addition to just viewing a lot of file format information it provides tools that help you with reverse engineering or malware analysis. PortEx is written in Scala and Java.PortEx is free, open source and still in heavy development. Although I made Unit Tests for the most parts of the code there might still be bugs.Features Reading header information from: MSDOS Header, COFF File Header, Optional Header, Section Table Reading standard section formats: Import Section, Resou…

Syscall notification
by Pancake- 1 reply

Hello. Im developing a bot to game, and tryin to be as stealthy as possible i planned to do some stuff in kernel. On x32 it was pretty easy to hook ssdt, and it was basically it, but on x64 things are different. I know the patchguard limitations, and i cant find way to intercept the syscalls. I want to hide and preserve debug registers because im using HWBPs to intercept game loops (i know i can do it usermode, but i want the stronger way), inject the implant botting code and control it from driver (already managed to do it). The only "legal" way to get notified was ObRegisterCallbacks but it works only for process creation and some other operations with handle, i digged …

Hello. Im tryin to filter out clicks which are comin for external applications and not user himself. I tried GetAsyncKeyState, GetKeyState or GetKeyboardState, watched the LPARAM and WPARAM in SetWindowsHook and it seems that automated keystrokes are the same as the usermade... I wonder how some games detect the fake input, any ideas?Greetz

Hello. I got a function which returns hash from const char*, and obviously the same input gives same 32 byte hash. My problem is that after compilation program recounts the hash everytime, is it possible to tell compiler to count it during compilation time and just save the hash value? Im creating wrappers for common functions like getmodulehandle, getprocaddress etc with PE parsing, and the problem is that such piece of code for example myGetModuleHandle(hash("kernel32.dll")) generates assembly which counts the const char* hash everytime, and i would like the compiler to make it myGetModuleHandle(0xdeadbeef) where its the counted hash. How can i achive that?

size of the code after compilation
by JustAGuy- 18 replies
- 5.4k views
Hi, is it possible somehow to get size or end address of a procedure, preferably without modifying procedure itself? e.g: Procedure Asem; begin asm mov eax, 5; add eax,8 shl eax,1 end; end; I want from my application determine size(number of bytes) of its own procedure, let's say, when I press a button. It's quite easy by using pointers to get start address of first line mov eax, 5, but how to get address of the last line(eventually RET)? For the sake of simplicity let's say the procedure is pretty simple with only one exit point and no external jumps outside of itself.

[dnlib] Injecting class with method.

Hello guys. I have some problems with injecting new class with one method inside it. Basicly this class is placed in my project and i need to insert it in assembly using dnlib, then call the method from it from constructor. My code sample: AssemblyDef assembly = AssemblyDef.Load(FilePath); ModuleDef module = assembly.Modules[0]; Importer importer = new Importer(module); // Create new importer. IMethod meth = importer.Import(typeof(MyClass).GetMethod("Initialize")); // Trying to import initialization method and then place it into a new class. TypeDef type = new TypeDefUser("NewClass"); // Creating new type. type.Attributes = TypeAttributes.Class; // Setting class …

File Encoder using key in byte array [C#]

Hello guys! I'm now on finding out how cryptor works (more on my previous topic) So there is some stub, with randomly generated method names, and randomly generated byte array that crypts the file: Sample of decryptin code: string text = (string)ResourceManager...byte[] array = new byte[text.Length];// and decrypt method string text = (string)resourceManager.GetObject(...... //using the string from crypted resources (i dont how its even store in resouces like that) byte[] array = new byte[text.Length]; for (int i = 0; i < text.Length; i++) { array[i] = (byte)text[i]; // decryption }//the most simple maybe... how to make encoder from this? …

Hi, here's another player lib, and I guess it comes with one of the best compromises between audio quality and size. The sound is awesome, but don't get fooled by the size of the included sound module examples (.ptp files), because they already come in a ready-to-get-compressed format. Check out the homepage for further info: http://code.google.com/p/protrekkr/ All credits to hitchhikr ofc.. a real magician. (Find some of his demos, if you don't know this guy yet.) And again thanks to eNeRGy/dAWN for the hints and the static lib! So here's the static lib and some example code in asm: PtkReplay.7z cheers

Hello, I am trying to debug/reverse engineer a program made in delphi, using x32dbg. This program use madExcept (which replace the default Delphi exception manager). If i put a breakpoint somewhere in the debugger, when it ran over the breakpoint, it does not break in the code, instead madExcept kicks in and the application show an error message : This is nice because the "bug report" can show me a stack trace and also a disassembly with full methods names It does not however , stop and break in the x32_dbg debugger (which i really want to), and thus does not allow me to run the program step by step. In the disasm window (…

Alternatives to JitHooking
by noob.exe- 4 replies
- 6.6k views
Yo, I am planning to code some method encryption, and I wanted to ask if there are alternatives to JitHooking. The problem is not hoe to encrypt/decrypt the methodbodys, - that's simple, the question is how I can detect the calls so I know when to decrypt. JitHooking is pretty unstable and might not work properly in future versions of the .Net FW. I am open for ideas and suggestions.

change PE header in suspended process
by JustAGuy- 8 replies
- 6.6k views
It's possible to create suspended process, change for example entrypoint and when resumed it would start from changed EP? I have a non-working executable(wrong EP) idea is to modify PE header but only when it's loaded in memory. I used WriteProcessMemory api to write correct EP to header but when resumed, process crashes. WriteProcessMemory returns success, so problem must be somewhere else. Is it too late to modify header when the process is suspended? thanx in andvance
