Spam volume increased 16 percent between the first and second quarter of 2010, according to Google, which tracks 3 billion e-mail messages per day with its Postini e-mail security and archiving services. But spam levels have declined year-over-year, dropping 15 percent between Q2 2009 and Q2 2010.
There’s a much different story on the virus front. Virus traffic in Q2 2010 was more than two and a half times greater than it was in the second quarter of last year, but has remained steady since the first quarter of 2010, increasing only 3 percent.
There’s also been a rise in “friend-in-need” phishing attempts, in which a hacker breaks into someone’s e-mail account and hand types a message to the victim’s contacts asking for money. Google has released “several updated filters” to combat these new waves of spam.
