In highschool we went through something like a malware/phishing prevention course.

It was pretty cool tbh, we spend the whole hour in a virtual environment where you'd see common malware and phishing attempts, but the really fun you could also "hack" other students.

Hacking them means you could cause some things to happen on their "PC". One of those was showing in a captcha on their screen and they had to type a the string of your choosing, before they could access the rest of the "virtual computer" again.

You can probably guess where this is going.
I was the first who had the idea to mix big i and small L and tested it on our teacher, who was also part of this environment and screenshared to the projector.

Thanks to sitting next projection I could see the pixels and I can confirm: same character, Pixel perfect!

I will forever cherish the memory of my the teacher begging me to undo the "hack" and the chaos that followed amongst my peers 😈

Also one of the excersizes was stupid. Click on a phishing mail and enter your credentials in the form. I asked the teacher WTF kind of credentials they even want me to enter to microsooft.cum and they just said "the credentials obviously" so I think they got their karma🖕
