Let's confirm you are human

[adam_c_voyton]

Several colleagues and I have observed a new pop-up when accessing the Canvas homepage, which is unfamiliar to us. This pop-up requests users to confirm their humanity by completing a puzzle involving clicking on the endpoint of a car's path to a destination, resembling certain CAPTCHA tests designed to prevent bot access to websites.

This situation raises concerns regarding whether the Canvas system unintentionally deployed a new feature to the production environment during the middle of the week on Wednesday, September 20, 2023.

I haven't heard of captchas being used to access Canvas homepage content.  I know a few years ago they created an option for self registration, but anything beyond that might be a measure that your technology team has instigated.

Most of the recent deploy and release notes have centered more around things like quizzes and general updates.
