SAN FRANCISCO — Yes, guys, those spam e-mails for Viagra or baldness cream just might be directed to you personally.
So, too, are many of the other crafty come-ons clogging inboxes, trying to lure us to fake Web sites so criminals can steal our personal information.
A new study by Cisco Systems Inc. found an alarming increase in the amount of personalized spam, which online identity thieves create using stolen lists of e-mail addresses or other poached data about their victims, such as where they went to school or which bank they use.

They're sent in smaller chunks, and often come from accounts the criminals have set up at reputable Web-based e-mail services.
Some of the messages are expertly crafted, linking to beautifully designed Web sites that are bogus or immediately install malicious programs.
Cisco's annual security study found that spam is growing quickly — nearly 200 billion spam messages are now sent each day, double the volume in 2007 — and that targeted attacks are also rising sharply.
