What does this do if you convert it? I would do it myself, but

Do it in a VM

It was an exploit which just spammed 4chan, I forget the details. Pretty sure it doesn't work anymore.

What I can remember off the top of my head.

Would post a random image from your computer to 4chan.
Would create an image like this one and post it there, with your image embeded* into it.
/g/entoomen create scripts to extract these images and get something sensitive from the folks who converted it.
Moot implements captcha.
Virus is kill.
Don't know exactly, all I know is from encyclopedia dramatica, go read it.

Nothing on GNU/Linux :^)

Here's some info about it. I never tried the image you posted but since it's a 4chan banner it probably just displays a message or something relatively harmless.

My favorite part is
>Even though Cornelia had once again been temporary defeated, it didn't stop /g/ from having a laugh at the expense of the retards who had infected themselves

Thanks for the answers guys. Couldn't this still work if you had a 4chan pass though? Since that bypasses the Captcha?

Maybe.
Unless the HTML stuff has changed.

It would work for 1 person

Borrow some code from 4chanx to cache captcha replies, users don't think much about filling out 2 or 3 captchas when posting :^)
