New Windows XP Malware in the Wild, not detected by ANYTHING!

Recommended Posts

If anyone can offer suggestions, we are encountering a new threat that we are unable to isolate. Any input on tracking it down is appreciated.

First be aware that we have scanned with every live CD and tool available. It is easier for us to just re-image the system than spend time tracking it down, but after having three such systems at work and now another from a home user, I am determined to get some samples gathered and squash this. I have one infected system I can hold off on nuking for a couple of days.


When the system is booted up and logged in, the internet activity will go hot. one of the svchost processes (the netsvcs one) will start consuming resources. Looking with TCPView, that svchost will be opening many seemingly random http calls to IP's. As http calls close, more open. Additionally, after a while of this, the AV will start detecting various java exploits as they are downloaded to the system.


So I am guessing that the malware has either infected one of the services being launched by svchost or svchost itself has been compromised.

Possible Course?:

So I am figuring that I could start by replacing each of the service DLL's launched by svchost one at a time and checking if the problem goes away. If it does, then I have nailed it down.

At work, we are corporate customers and have Technician's licenses for MBAM. However, the only computer I have access to for any length of time is a home user, so I am not using corporate MBAM products on it.

So I would not feel comfortable proceeding as requested unless that is YOUR decision.

For the home user, this is what you can do....

Hello and welcome to Malwarebytes

If you think you are infected, here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult

You have 3 Options that you can choose from as listed below:

  • Option 1 —— Free Expert advice in the Malware Removal Forum
  • Option 2 —— Paying customer -- Contact Support via email
  • Option 3 —— Premium, Fee-Based Support


As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the

Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

  • Please read and follow the directions here (http://www.malwarebytes.org/forums/index.php?showtopic=9573), skipping any steps you are unable to complete.
  • After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification,
    so that you're alerted when someone has replied to your post.

NOTE: Please do not post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies.

If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

  • If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
  • You may send a Private Message to a Moderator asking for assistance.


Alternatively, as a paying customer, you can contact the help desk at support@malwarebytes.org or here (http://helpdesk.malwarebytes.org/home)
