Mutating code!!
February 20, 2010 at 3:52 pm
Why would this file that exists on my server and only I have access to...

Code:
<HTML>
<HEAD>
<TITLE>The Naughty Corner</TITLE>
</HEAD>

<BODY bgcolor="#999999">

<style type="text/css">

<!--
#modalContainer {
    background-color:transparent;
    position:absolute;
    width:100%;
    height:100%;
    top:0px;
    left:0px;
    z-index:10000;
    background-image:url(tp.png); /* required by MSIE to prevent actions on lower z-index elements */
}

#alertBox {
    position:relative;
    width:367px;
    min-height:150px;
    margin-top:50px;
    border:2px solid #000;
    background-color:#dddddd;
    background-image:url(kyu.jpg);
    background-repeat:no-repeat;
    background-position:4px 50px;
}

#modalContainer > #alertBox {
    position:fixed;
}

#alertBox h1 {

    margin:0;
           height:40px;
           background-image:url(aatitle.gif);
           background-repeat:no-repeat;
           background-position:0px 0px;
    border-bottom:1px solid #000;
    padding:2px 0 2px 5px;
}

#alertBox p {

    font:0.7em verdana,arial;
    height:50px;
    padding-left:5px;
    margin-left:80px;
}



#alertBox #closeBtn {

    display:block;
    position:relative;
    margin:5px auto;
    padding:3px;
    border:1px solid #000;
    width:70px;
    font:0.7em verdana,arial;
    text-transform:uppercase;
    text-align:center;
    color:#FFF;
    background-color:#78919B;
    text-decoration:none;
}

-->

</style>

<script type="text/javascript" src="customAlertBox.js"></script>
<script language="JavaScript">

<!--

...And it goes on for a while...

Suddenly and without any help from me, turn into this..

Code:
DPbBfs  <a href="http://jrxiihmawjrm.com/">jrxiihmawjrm</a>, [url=http://cmzsqilvjtqw.com/]cmzsqilvjtqw[/url], [link=http://jyowdcuweyje.com/]jyowdcuweyje[/link], http://oamsptprmgbq.com/

I did a google check on dpbbfs and found one other site with a comment in its guestbook that looked exactly the same Dodgy

The only thing I've noticed out of the ordinary is that you're still using <script language="JavaScript">, there's no attribute "language" as it is now deprecated.

Its been outdated for a while now, said attributes were kept around for backward browser compatibility, but I rarely see them nowadays so I'm assuming they've been dropped together with some elements too. Not to mention the self-proclaimed Linux boffins I knew at college regarded it as poor coding practice.

Code:
</style>

<script type="text/javascript" src="customAlertBox.js"></script>
<script language="JavaScript">

<!--

...And it goes on for a while...
I would try just sticking with <script type="text/javascript"> and drop the second line to see if there's any improvement. :]

But that wouldn't actually change the file would it?

Does the file change immediately/ is it manipulated externally do you think?

Don't know. It's only happened the once to my knowledge but it's still wierd. It's a bit like uploading a picture of your family called family.jpg and then comming back a while later to discover that the same file now shows a picture of a squid :S

Is it possible the server was hacked?

Possibly, but why just change one obscure file to something like that? Makes no sense :S

Permissions on it? Maybe an indicator of something more going on?

Perhaps that file was changed by a virus or hacker of some sort in order to serve some purpose such as a backdoor or something with the hopes that you would not notice just that obscure file.
Has anyone really been far even as decided to use even go want to do look more like?

The problem with that suggestion is that (a) the replacement isn't an executable file (i.e. it doesn't do anything, so a backdoor is impossible), and (b) in order to replace the file in the first place, the virus / hacker would have to have access to the system, which means there isn't any need for a backdoor.

I also assume this is a Linux server? If so, the chances of it being a virus are non-existent, and the chances of it being some sort of file execution is also unlikely. The only real explanation is that you had some externally accessible script that someone exploited...whether intentionally or not.
