Hi there, i have a question for Delphi code. I want to be able to read all text from other processess windows. Now i am aware of FindWindow API, but it only reads Caption of a main form - and I want to be able to read from status bar, menus, memoboxes, from everything that might contain text. So is there a way to get this (except capturing a screen and using ocr to recognize eventualy text)? Any ideas, comments?

Hii! i am almost about to release my first old-school intro with some friends! the only thing left is to know how to bind textures to a quad i am working with opengl 1.1 as much as i can, for this intro to work on old windows/old integrated graphic chips, so i want to avoid libraries and do it as vanilla as posible also to learn from it! = p i created a new opengl template in Code::Blocks to work in a cleaner environment, the code is as follow: https://pastebin.com/raw/XpS0hRpj which output this nice square on the screen: BUT instead i want to use this nice snowflake: and since afaik i can't use png files without a library, here is the …

.net IL Memory Patching?
by PermaNull- 4 replies
- 9.7k 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
- 8.7k 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…

[DELPHI 7 SOURCE] Simple Layered Encryption
by JohnWho- 3 replies

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. …

Syntia is a program synthesis based framework for deobfuscation. It uses instruction traces as an blackbox oracle to produce random input and output pairs. From these I/O pairs, the synthesizer learns the code's underlying semantic. https://github.com/RUB-SysSec/syntia

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?

Are there any C++ hooking libraries that also allows a function to be called right before the return statement? I would like to get some values from two registers after the function has executed, without having to hook all the places where this function is called.

Hello, I have been trying to make different self modifying programs in c++, but there have been some problems I am facing due to my less knowledge and experiences. I would be grateful if anyone helps me about these 2 question. 1. how to make the exe's code section writable programmatically? normally, after compiling the program, I use cff explorer and change the "is writable" flag of that program to allow it modify itself. But what code can I write inside the main() function to make it compile with the write allowed? 2. So, far, to make some certain lines self modifying, I am doing it this way : asm("nop"); asm("nop"); asm("nop"); asm("nop"); asm("no…

Hello, how do you make a .net coded program self modify itself at run-time? I am not talking about making a loader program or something like that. Like, in native, you can make the program xor itself from and upto certain addresses at runtime, is it possible to do the same in .net? Then how? Now, about modifying IL codes. So far, I know about basic code injection in a method using mono.cecil library, but I can do it only in a non-running app. I intend to add some codes in sub_new () or entry point method to make the program add/remove/modify few IL code lines in a specific method. Like this, sub new() // get the certain method // add/remove IL code fr…

Hello, I'm developing a processor module for IDA (using the C API) and I've run into something that has me quite annoyed. Sometimes, when I call the blocking functions from kernwin.hpp (warning(), for example, which displays a MessageBox), they would cause IDA to crash. Removing those function calls from the processor module makes it work fine. I'm calling those functions from within my emulator function, and when IDA calls my outputter afterwards to output the instruction it crashes inside the call I make to MakeLine(). Digging a bit deeper, it seems like IDA loads and unloads some sort of context related to the GUI or outputting of disassembled t…
