Postini: Spam Still Worsening
"What we're seeing is a profound increase in the sophistication and incidence of tactics designed to fool conventional anti-spam filters," said Chris Smith, senior product marketing director at Postini, Redwood City, CA.
The report also said virus attacks via e-mail grew threefold and directory harvest attacks continued to plague corporate e-mail servers.
Spammers also are targeting smaller companies -- those with 100 users or fewer -- because they have less-sophisticated defenses. Smaller firms get up to 10 times more spam than corporations, the study found.
And certain industries, including publishing, advertising, legal and real estate, received more than 10 times the amount of spam per user per day compared with organizations in banking, financial, manufacturing, electronics and pharmaceuticals.
