Bots are better than humans at cracking β€˜Are you a robot?’ Captcha tests, study finds

For over two decades, Captchas have been deployed as security checks by websites to block potentially harmful bots by presenting puzzles that are supposed to be straightforward for people to solve – but very difficult for computers.

Engaged in an arms race with bots, Captchas have since evolved into an annoying presence on the internet, becoming increasingly more and more difficult to solve for both bots and humans.

However, the new yet-to-be peer-reviewed research, posted in arXiv, finds bots are able to quickly crack Captcha tests with ease, suggesting global effort users put into cracking these puzzles every day may be more trouble than it’s worth.

The irony of this is just too much, and it’s made me feel pretty stupid sometimes. I remember struggling for ages with the Epic Games website captcha (along with many others who were complaining). I see Cloudflare had been working on a more modern method (something to do with how the mouse moves to click inside the tick box) which is quicker and always seems to work for me.

But yes, I don’t suppose the results of this survey will surprise anyone.

GPT-4 easily solves CAPTCHA.

I got to try GPT-4's multimodal capabilities and it's quite impressive! A quick thread of examples... - Tanishq Mathew Abraham (@iScienceLuvr)

In theory, I am currently employed by an organization with a strong technical background, a technical university. Sadly, it doesn't very often feel like that. (technical, I mean) Now for example I wanted to log into our administrative system to approve the absence of a few students. Here is the login window:
enter image description here
I had already entered username and password. In addition I need to check the checkbox you see in the background. The text "I'm not a robot" next to it is covered by the beautiful captcha that popped up in response to me checking that box.

I have tried during previous school meetings to explain that a captcha at a login with existing credentials is not actually meaningful, not increasing security, only time wasted for meaningless activities. Luckily I got in after checking the three chimneys. A while ago, when they introduced this system, I made a video once where I tried without success to log in for several minutes, because after I completed a captcha I got a second page with more images and after completing that I got a new captcha and so on and nobody worried about that at all.

As I said, it doesn't always feel very technical around here...
