Re: [Asrg] Spammer proxies using legitamate mail relays

You've heard of hashcash, naturally.

And exactly how long do you expect it will take for spammers to install a hashcash computing trojan on their 5 million zombie PCs? That's *way* more computing power at their disposal than anything we have available.

Is it? There are 5 million zombies, perhaps, but there are many *more* legitimate e-mail users. At the very least, that allows us to get the "percentage of e-mail that is spam" down below the 50% mark that it passed many months ago. Remember that spammers have to spread those zombies out among all their campaigns and targets.

Right now, each zombie can send tens or hundreds of messages a second. Reducing that to one or less per minute would, in itself, put a big damper on their operations.
