cyril7: Hi, we have no twitter access here at work, could someone kindly post the guts of the Metservice notice, I see they have plucked their syndicated ad roll.

Cyril

The tweet says:

@freitasm @nathanm @Rosspnz @stevebiddle Virus on ad server closed down last night - @MetService site not affected - more details soon! ^JB

So... not good really.. Especially with the weather recently.

Ragnor:
freitasm: It was the metservice website: http://twitter.com/#!/MetService/statuses/103597899644026880

Anyone know the specifics of how the infection worked and what it infected, seems to be another IE only exploit on unpatched Windows XP and 2003...

My system was a fully patched server 2003 with MS security essentials running IE8.

My machine is still borked now with find.exe running multiple tasks sucking 100% CPU.

How did you manage to run Microsoft Security Essentials on a Server 2003 box? I though MSE wouldn't run on Server platforms?

I suggest people try HouseCall from http://free.antivirus.com - it works on servers as well.

Not good at all, Metservice was probably the most visited web site in the country for the last few days.

Just received:

At around 8pm last night, Tuesday 16 August, MetService’s web support team identified an issue with its ad server. The ad server was immediately shut down to protect client browsers and prevent further problems; at no time was metservice.com unavailable to the public. Prior to this we had received no reports of any issues.We now know that the ad server was compromised by a malicious attack, through a vulnerability which allowed someone to upload a binary file into the database. This file contained JavaScript code which redirects the browser to a website which downloads malware files to the client machine.

Over the past week, MetService’s website has experienced record numbers of visitors due to the severe weather being experienced across the country. The site has handled this record traffic well. The popularity of the site no doubt made it a target for this attack.

An upgrade incorporating a fix is now being installed in order to resolve the issue. The ad server database is also in the process of being cleaned and rebuilt. We have responded to tweets on the issue starting just before 10am this morning, and will continue to respond to users’ concerns as they arise.

FYI.

The URL that the Java code that was being downloaded from to browsers and executed. It came from various *.dyndns-web.com addresses, and kept changing the filename.

Interesting. Any idea which exploit was used as a vector - specific missing patches, OS versions, etc?

Could someone who has been able to scan, detect, and clean this up post the full name of the malware, and the name of the cleanup utility please?

Hmm this will explain the multiple web browser redirect attempts that Metservice's iOS app was trying to make on my iPad last night.

Fairly sure the redirect would have been as far as it got though...

So it sounds like the ad server got compromised which led to a java (not javascript) applet being served to the browser in the metservice pages, the applet used an exploit the java vm to install personal shield pro on the machine.

Nasty.

Might pay to update java http://www.java.com/en/download/

One of the guys here removed "personal shield pro" from the receptionist's pc, he used malwarebytes to remove it. Will see if I can catch him to find out the if there was full name.

I would also try TDSS Killer too from Kaspersky just in case:

http://support.kaspersky.com/viruses/solutions?qid=208280684

When I got TDSS malwarebytes said it was clean, but there were still bits left over TDSS bits and kept on re-infecting my wifes PC.

Easy way to check is shutdown every instance of Internet Explorer and see if "iexplore.exe" is still a running task in task manager. Kill it, if it comes back magically. Then you're still infected.

Security Essentials works fine in server 2003, and it's the reason I use it as most server AV programs aren't cheap compared to desktop apps.
