Hi, One of our workstations is broadcasting a huge amount of UDP traffic (around 5Mbps) and I'm thinking it could be a zombied computer doing DDOS as directed by its controller. But the weird thing is - it has an updated McAfee AV with HIPS ?? Why was this not detected - or could I be reading this wrong? Here's a portion of the tcpdump:
1) take if off the network. 2) burn a rescue CD and boot the machine with it. I suggest ubcd4win - http://www.ubcd4win.com/howto.htm - an enable the Sunbelt VIPRE and any other plugins (malwarebytes, especially) you deem appropriate to see if you can clean/identify the culprit. I just tried ubcd4win yesterday, and it was dead easy to work with. Excellent tool. There are other good tools, but I just used this one and like it. 3) regardless of whether you clean the machine and/or identify the culprit, save the data, rebuild the box and patch it so that it doesn't get infected again. Personally, I don't like McAfee at all. We switched away from that to the Sunbelt product, and haven't looked back.
