Hello, at the moment I trying to lern how to work with RegEx syntax and I have to say it makes fun and seems to be also very usefully.I also like the online site regex101 for testing / checking and to get the results and infos in realtime.(I would like to have any offline tool similar as regex101 [not notepad++]) Now my question is whether there are also any libs for MASM already I could use for myself in my apps if I need or want to check text sources for anything,so with RegEx it would be much better than to search manually with limited small pattern.Maybe any lib with functions I can also use with same string syntax etc.Does anyone know some latest thing etc…

If dwNumberOfBytesToMap is zero, the entire file is mapped. How to handle large files?What is the normal way for that?Should I first check how much virtualmemory the system has (in my case 4 GB - 1 GB for g…

Hi there, i have a question for Delphi code. I want to be able to read all text from other processess windows.

.net IL Memory Patching?
by PermaNull- 4 replies
- 9.8k views
I'm wondering if there's any library available for patching IL code in-memory at run-time of a remote App, similar to how you'd perform detours or write memory to a remote C app. Basically I'm dealing with an application I'd like to bypass some checks on but getting defeated by the packer's integrity protection when manipulating the IL in the binary itself, so I figured my next best option was to write a loader and patch the process in memory. I've looked through a few different things: https://github.com/0xd4d/dnlib - I haven't discovered any in-memory patching functions for IL code in specific locations in dnlib if it exists please do let me know. Most o…

Problem calling hooked function (MinHook)
by Zeupert- 5 replies
- 8.9k views
In my DLL I am using the MinHook library to hook certain functions based on their address. The problem is, if I try to directly call the original function with the address that MinHook gives me, it ends up crashing, it only works when jumping directly to the address. I am working in x64 btw. I am hooking the function in a way like this: extern "C" LPVOID originalFunc; LPVOID myAddress = 0xDEADC0DE; MH_CreateHook(myAddress, &myCustomFunc, &originalFunc) the "myCustomFunc" is also declared extern "C" and is a function in a seperate assembly file, looking like this: myCustomFunc: *push all registers, similar to pushad* call myFunction *po…

I have been working on a EXE protector for a looooooooooooong time and in the process i have coded a lot of test functions, here is a first and very basic version of one of them. Instead of just sharing the code snippets i put the functions to use by showing it in action. The example does: 1). Add a new section to a 32-bit .exe 2). Change entry point to new section, 3). Add variables to layer encrypted function and encrypt the 5 layers 4). Write layer encrypted function to new section When target file is executed the 5 layers is decrypted, on last layer OEP is decrypted and jump is taken to OEP. All is simple xor encryption. …

Allocate Console in Java

Allocate Console in Java??? When I try to run the bolded one it doesn't work: JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); int compilationResult = compiler.run(null, null, null,sourceFile.getPath()); The run method can use streams to handle input and output: int run(InputStream in, OutputStream out, OutputStream err, String... arguments) When I run the program from console with java.exe or even javaw.exe all works ok. SO I think it fails because it doesn't have a console window or such... Anyone know how to solve the problem?
