Assuming spammers can build 4-way boxes out of these, how many

Assuming a 5KB spam size, about 7500 of them. Is this economically
feasible for the spammer? You tell me.
Of course it is. They infect 10,000 new zombie PCs every day.
Multiply that by 6. We're seeing 65,000 - 70,000 zombie detections per
day, and the daily detection count is still trending upwards.
80% of spam detected by this method (it's catching approximately 65-70%
of all of our spam) is coming from detections less than 4 days old. 90%
< 6 days old. 95% < 12 days old.
Are we having fun yet?
