Anti-Debugging

Description

Anti-Debugging detects debugging sessions of your application to trigger defences that thwart reverse engineering attempts. Countermeasures can be specified (optionally) to be executed when someone tries to debug your source code.

Anti-Debugging is fully compatible with the browser's Content-Security Policy (CSP).

Code Annotation Example

// @jscrambler define antiDebugging {countermeasures: {redirect: /logout}} as ad
