Although the numbers had leveled off for two years, virus-infused spam messages have spiked once again, says SCMagazine.
Data collected by Postini based on Google's e-mail and archiving services shows that its security provider blocked more than 100 million messages that contained a virus payload. The senior product marketing manager for Google's Postini group, Adam Swidler, reported:
The last time we saw volumes [of spam] this high was in 2007, when there was an outbreak of the Storm [worm] attack.
The Postini group also says that the size of spam messages is increasing due in part to the resurgence of image spam and other viruses that require larger payloads.
