Utilize Java Agents and ASM to modify then override Java SE classes. (In this case blocking java.lang.Runtime.exec)

JVM Sandbox - Utilize Java Agents and ASM to manipulate then override Java SE classes.

Just a simple POC to block Runtime.exec for any Java jar

This should work on all VMs on all OSs, if it doesn't please send an email to [email protected] with your OS and JVM information, thank you.

How to use this: 0) Download the zip file containing the jar and .bat/.sh files.

  1. Click the .bat or .sh depending on your OS
  2. Import the jar you wish to sandbox/debug
  3. Enter the main and method class it'll invoke
  4. If you want to just test to see if it works, run the test.jar class.

Features: Blocks all Runtime.exec calls Blocks the process builder Blocks awt.Robot Can block JNI (LOL)
