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. Description: 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. Analysis?: 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. Thoughts?
