Anti-Debugging Techniques in JNI(Java Native Interface)

This repository contains a C program in JNI(Java Native Interface) demonstrating various anti-debugging techniques. These techniques are designed to prevent or hinder the debugging of the program, making it more difficult for unauthorized users to analyze or reverse engineer the software.

Features

• Virtual Machine Detection: Checks if the program is running inside a virtual machine by examining the Local Descriptor Table (LDT).
• Debugger Presence Check: Detects if a debugger is currently attached to the process.
• Memory Dump Prevention: Attempts to prevent memory dumps by changing the memory protection of the process.
• Remote Debugging Prevention: Blocks remote debugging by modifying process information.
• Thread Injection Prevention: Prevents thread injection attacks by modifying memory protection.
• JDWP Interface Monitoring: Monitors and disables the Java Debug Wire Protocol (JDWP) to prevent remote attachments.

Customize

It's easy to combine this project into your project to protect your project from unauthorized debugging.
