MPP and Beyond

The last few weeks have seen huge explosions in spam due to new techniques that have befuddled detectors once again. Of course the problems are only momentary but in a period of a few weeks we have seen all new types of attacks - pdf spam, followed by xls spam, and now text files in .zip archives. It presents all new challenges for spam detectors because now they have to venture even farther into the world of antivirus engines to provide adequate protection. It seems like we will need unpackers, code emulators and the like to fight spam, now that the spammers are exploiting user behavior in the same way as virus writers. As spam and viruses seem to be on a more rapidly convergent path, perhaps AV engines will have new found validity?
