Hi all, Black Hat was a blast, but I still missed having Tom nearby for support and brains... As promised, you can find the MyDoom blocking script on www.isatools.org/block_mydoom.vbs. I don't have a "cleaner" script this time because this one attaches itself to the explorer process and if the script kills that process, it effectively commit suicide. Symantec, Computer Associates, etc all have perfectly functional removal tools and steps.
