ASMInjector 💉🔍

ASMInjector is a powerful Java application that allows you to inject code into existing JAR files using the ASM ( Abstract Syntax Tree Manipulation) bytecode manipulation library. 🧰 It provides a user-friendly graphical interface to load a JAR file, select a class and method, and embed your custom code into the selected method. 🚀

Features ✨

• 🗃️ Load and explore JAR files
• 📂 Browse and select classes and methods within the JAR
• 💻 Inject custom code into any method of your choice
• ⚙ Option to run the injected code in a separate thread
• 🔄 Generate a new JAR file with the embedded code
• 🖥️ Cross-platform GUI built with Swing
