Latest Sober threatens e-mail gateways | Tech News on ZDNet
The latest Sober worm, first spotted over the weekend, has generated the vast majority of virus-laden e-mail traffic in the past 24 hours and could cause problems for corporate e-mail gateways, security companies said.

This variant of Sober generates e-mails that purport to be from the CIA or FBI. These messages tell the recipient they have been looking at illegal Web sites and should answer some questions in the e-mail’s attachment. If the attachment is opened, the computer is infected, and the virus sends copies of itself to any e-mail addresses found on the hard drive.
