What would happen if I opened the file in this 4chan banner?

Nothing. It's a reference to a spambot that was active a few years back.

How would you even open it?

As the picture says, copy paste it to mspaint and save as 24-bit bitmap. (propably just the grey part) I was too scared to try it.

>>34658
Just did it.
Looks no different.

Changed the extension to .hta and got a weird text line akin to &*&*&*&*&*&*&...

God damn lardvynil. All those images, lost forever...

What exactly happened to you?

Are you this retarded? You infected yourself with a trojan/worm, dumbfuck.

I was thinking about a possible useful new /b/ chemo.
How do you force a buffer overflow when opening an image? I remember some boards that used it to raep newfags and it'd be fun to watch /b/ burning again.

It outputs itself as a PNG, with slightly different text.

Back in the day it would post itself to 4chan, but that was before recaptcha.

The banner version has the posting functionality taken out.

Actually, this was after the captcha. moot is dumb and installed the captcha incorrectly, allowing spammers to rape 4chan with spambots.

>How do you force a buffer overflow when opening an image?

Generally you don't, because image viewers are way up the hierarchy of "programs that deal with unsanitised input from hostile actors", and thus parsing vulns are taken very seriously and dealt with quickly, even preemptively.

LibPNG, for example, has only had eight serious remote-execution vulnerabilities since 2008.

Cornelia was one of the most interesting spam attack on 4chins.

Not Cordelia. girlvynil, the fat cunt who used to own encyclopediadramatica.

She deleted it to make Oh!Internet a few years ago, and a fuckton of its content was lost forever.
