Spammers are cycling through their lists of product-pitching URLs
faster than ever, McAfee Inc. said Wednesday.

In August, major spam campaigns ran through 72 percent more domains per
hour than the month prior, the Santa Clara, Calif. company said.

Spammers often use multiple URLs in their campaigns to avoid anti-spam
blacklists, then change the embedded links as each batch of junk mail
goes out. The dramatic increase in the number of different domains
shows that spammers are stepping up their attempts to stay ahead of
security defenses.
