I’ve actually noticed this in some websites the past ~two months. It’s neat to have a captcha that finally doesn’t need slowly clicking images to pass through.

      Yeah, I’m pretty skeptical of the premise… it’s looking for browser “abnormalities”? I mean… there wasn’t a strong motivation to correct those abnormalities for bots when it didn’t matter. Now that it does, I just suspect they’ll correct those abnormalities.

      Just because the abnormalities were present in the past doesn’t imply that it’s intrinsically more difficult to emulate browser behaviour than it is to defeat captchas. There just hasn’t been a reason to do so up until now.

      Nothing can stop 100% of bots. The goal with captchas like Turnstile is to use a significant portion of your resources to the point it’s expensive and slow to perform an attack.

      Turnstile runs many background checks on your browser, so headless browsers automatically become futile.

      JavaScript PoW challenges are performed that take up multiple seconds of execution time, memory and CPU. This alone is a deterrent because sequential attacks become extremely long to execute.

      Concurrent attacks are still unfeasible because Turnstile ups the difficulty if it detects something is up, and receiving requests from thousands of botnet IPs is bound to trip an alarm.

      I’m curious how easy it would be to bypass with significant volume though?

      Like a few requests might get through but it would get fairly easy to detect dozens of requests from the same bot i think?

      It’s also doing some “light” proof of work - this would be a PITA if you were trying a bot net attack or something.

      I mean it’s always going to be an uphill battle, but I’d rather it stop some bots and be easier for me than them making me do a million captchas, that dont even work half the time, that still don’t stop many bots.
