The company's Postini corporate e-mail security service reported that the volume of e-mail virus attacks peaked at almost 10 million on a single day.

On its enterprise blog on Tuesday, Google plans to report that it saw more infectious spam messages in July than any month so far this year.

According to data gathered by Google's Postini corporate e-mail security service, the volume of e-mail virus attacks peaked at almost 10 million on a single day, July 24.

That kind of volume, six to seven times what's typical, means spam messages are getting through someone's defenses and turning recipients' machines into zombies, said Sundar Raghavan, a product marketing manager with the Google Apps Security & Compliance team.

"The summer of spam has caught up with us this time," said Raghavan.

Raghavan suggests that in contrast to the message protection Google delivers from the Internet cloud, anti-spam hardware appliances that don't update fast enough may allow malicious e-mail attacks to succeed.

Much of the spam that Google is seeing aims to exploit not browser or operating system vulnerabilities but user curiosity. Thus, explained Raghavan, spam now takes the form of spoofed CNN newsletters with link descriptions designed to bait the user, such as "Microsoft Bribes Chinese Officials." Clicking such links in spam messages, however, generally leads to malware.

Raghavan also said that Google has seen an increase in e-mail messages with viruses concealed as encrypted .RAR attachments, despite an overall decrease in malicious attachments.
