Kkzkk.com

Kkzkk.com was a screamer Korean website that was registered in 2004 / 2015, it was later discontinued by the Korean Government in 2014.

Firstly, the website displays the alert messages that appear "What The Hell !!!" right before a montage of screamer pictures include: Pazuzu, Ahenobarbus Henocied, Regan MacNeil, a blue-tinted woman and many more will appear, which are accompanied by an incredibly, loud scream.

There is a malicious script that tries to open numerous pop-ups (that presents the same content) to prevent the user from closing, followed by another script that full-screens the browser entirely as soon as the images appears, if the user disregard closing the pop-ups, this can lead the CPU to reach 100%, which can make the cursor to move jiggly, making it harder to close, the script only works on Internet Explorer, if the user uses non-IE browsers, 1 pop-up will only appear upon entering.

History
In 2005, the website used to be an imageboard and does not contain any screamers whatsoever, in April 2012, the website has now later turned into a screamer and was later discontinued by the Korean Government for being very malicious site in 2014, it also contains the text: "Hello World :) Do u want to see ghost? (kkzkk@naver.com)", this is the same text used in Ghost, and might be the same creator.

As of May 1st, 2017, the website was later acquired by Ehren Schaiberger, and the content features a kitten (as the logo) and a privacy policy page, the site no longer contains screamers.
