Testing Anti-Debugging Detection


In order to test for anti-debugging detection you can try to attach a debugger to the app and see what happens.

The app should respond in some way. For example by:

  • Alerting the user and asking for accepting liability.
  • Preventing execution by gracefully terminating.
  • Securely wiping any sensitive data stored on the device.
  • Reporting to a backend server, e.g, for fraud detection.

Try to hook or reverse engineer the app using the methods from section "Anti-Debugging Detection".

Next, work on bypassing the detection and answer the following questions:

  • Can the mechanisms be bypassed trivially (e.g., by hooking a single API function)?
  • How difficult is identifying the detection code via static and dynamic analysis?
  • Did you need to write custom code to disable the defenses? How much time did you need?
  • What is your assessment of the difficulty of bypassing the mechanisms?
