    We recently stumbled across a bug on the Chromium bug tracker where a short JavaScript snippet can crash headless Chromium browsers like those used by Puppeteer and Playwright. Sounds like a dream bot signal, right? Detect the bots, crash their browsers, and all from client-side JS, no server needed. If you’re lucky enough, you may even be able to cause memory leaks on their servers!

    Maybe. Maybe not. In this post, we’ll break down the bug, explore how it could be weaponized for detection, and finally explain why this is probably not a good idea to use it in production.
