Unless the propogation of these malware programs is quenched, I
think this incident can be taken as the start of the end for mobile
users of naked, unauthenticated, unverifiable SMTP. There are other
methods by which they can send email, and those methods will help
protect against this kind of spam attack, at least.
While spammers can adapt and change their methods, I think that
other than willingly cooperating spam houses, this method of co-opting
thousands of random computers is probably the simplest and most
effective way of sending spam.
This is the specific problem that DRIP addresses. See
