Some statistics from a report by 'email security firm' Return Path;
- 95% of all email is junk (spam, viruses, error messages)
- Less than 4% is legitimate traffic
- 99% of the computers they 'monitor' have been taken over by spammers
- Only 1% of net addresses could be regarded as legitimate sources of
mail. The rest are hijacked computers, or bots, used by spammers to send
e-mail
Another company 'Ironport' claims that 80% of email comes from
compromised hosts.
you know, percentage numbers are pretty much useless without a reference
enabling you to turn it into real numbers. For example, 80 percent of
e-mail coming from compromised hosts means what? How much e-mail over
what period? good Lord, this is the very statistic we need to get a
handle on the zombie problem with respect proof of work puzzles.
(just being a pain in the ass today which is not much different from
yesterday or tomorrow)
