There have been no major incidents, and W32/Klez.H@mm is still the most common virus in MessageLabs statistics. However, there are some continuing trends:
W32/Warpigs.B takes password guessing to new lengths - it contains a list of 1600 passwords that it uses when scanning the network for vulnerable hosts.
The W32/Webber Trojan arrives in an email that uses people's sensitivity about their personal data to encourage the recipient to open the attachment. The email message appears to be a failed loan or credit card application from a well-known institution, and claims that the attachment is the recipient's credit profile. Of course, opening the attachment launches the Trojan.
Warpigs and Webber are not common, but there are other similar ones so reminding your users about Safe Hex might be a good idea.
