Kkzkk.com

Kkzkk.com was a South Korean screamer website that was registered sometime in 2004/2005. The website was later seized by the South Korean Government in 2014.

The website displayed an alert message that read "What The Hell !!!" right before a montage of screamer pictures (Pazuzu, Ahenobarbus Henocied, Regan MacNeil, and more) would appear, which were accompanied by an incredibly loud scream.

There is a malicious script that tries to open numerous pop-ups (that present the same content) to prevent the user from closing, followed by another script that full-screens the browser entirely as soon as the images appear. These pop-ups may cause the CPU to reach 100%. The script only works on Internet Explorer. If the user uses a non-IE browser, only 1 pop-up will appear upon entering.

History
The website used to be an imageboard in 2005 and did not contain any screamers. In April 2012, the website changed into a screamer website and was discontinued by the South Korean Government in 2014. It also contained 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.

The website was later acquired by Ehren Schaiberger on May 1st, 2017, and the content was changed to a picture of a kitten (as the logo) and a privacy policy page. The site no longer contains any screamers.
