[release] JVM Class Dumper (dump OSRS classes)

GitHub - SytheMarket/JVMClassDumper: An injectable DLL to dump classes from a running JVM (win32)

This will inject a DLL into a running java virtual machine (even if the JVM is embedded inside another application) and hook the defineClass method of the JVM's classloader. From the point of injection it will dump all class files to <jvmmodulelocation>/dump/

This can be used to dump OSRS classes from a running JVM.

Specifically you would start OSRS and then quickly run:

Code:

jvminjector.exe JagexLauncher.exe

you should see something like

Code:

D:\Downloads\Release>jvminjector.exe JagexLauncher.exe
path: D:\Downloads\Release\jvminjectdll.dll
Injecting PID 5604
Injected into 1 processes according to specified search
Finished. Press any key to close this window.

Now let the game load completely.

If you check C:\Users\<YOUR USERNAME>\jagexcache\jagexlauncher\bin\dump all the class files should be there.

Thus bypassing all encryption and compression of the game files.

Caution: DLL injection will fire your virus scanner. If in doubt I encourage you to compile the project yourself.
