This repository contains the "crackme" project, a program that utilizes various protection techniques, including:
- String encryption during compilation
- Dynamic code integrity checks during runtime using CRC32
- 4 anti-debugging methods
- 3 anti-disassembly methods
- 2 virtual machine detection methods
- Using an exception to control the flow of execution
- Self-modifying code techniques
- Minor obfuscation and fake checks
The program reads a password from a file called password.txt located in the same directory as the executable. Then it checks the password contained therein, and if the check is successful, it generates a serial key in the format "KEY$..." and writes it to a file named serial.txt.
The successful compilation and testing were done using the following tools and environment:
- Visual Studio Build Tools v143
- Windows 11 SDK (10.0.22000.0)
- Python 3.11.3
- pefile 2023.2.7
The compilation and program execution are supported only on Windows x64. Successful tests were performed on Windows 11 Pro 22H2 22621.2283.
To compile and run the program, ensure you have the specified development environment set up. Then, simply build the project and run the resulting executable.
