i encountered this for the first time today while attempting to read something on archive.today.
i confirmed that decoding the qrcode using a computer and following the URL it contains is insufficient; the error it gave directed me here which is what the linked screenshot is of.
the old type of captcha remains available too, for now:



No malicious site would ever fake this kind of flow in order to get someone to scan a dangerous QR code. Nope, that would never happen.
It’s already happening. They tell you to scan a QR code that links to a website where they ask you to log in with your Google account (but it’s just a phishing page).
Good job Google!
