JSADD - JavaScript Anti-Debugging Detection Tool

About

JSADD is a browser extension which detects common techniques implemented by websites that aim to impede, alter or detect debugging attempts using the integrated Developer Tools.

Supported anti-debugging techniques

JSADD supports the detection of the following anti-debugging techniques:

• ShortCut (Impediment) [1]
• TrigBreak (Impediment) (Chromium only) [1]
• ConClear (Impediment) [1]
• ModBuilt (Alteration) [1]
• WidthDiff (Detection) [1]
• LogGet (Detection) [1]
• Firebug Lite (Detection) (Chrome only) [2]

Currently supported browsers

• Chromium-based browsers (e.g. Google Chrome)

Due to the lack of support for the execution world MAIN of the scripting API in Firefox, JSADD is not supported for this browser yet.
