It's been quite a ride tonight with tons of new, slightly different Bagle variant being seeded.

So far tonight we've seen these Bagles:

 Email-Worm.Win32.Bagle.cy (aka Bagle.BI)
 Email-Worm.Win32.Bagle.cz
 Email-Worm.Win32.Bagle.da
 Email-Worm.Win32.Bagle.db
 Email-Worm.Win32.Bagle.dc
 Email-Worm.Win32.Bagle.dd
 Email-Worm.Win32.Bagle.de
 Email-Worm.Win32.Bagle.df

Bottom line: if your organization is still, in year 2005, accepting incoming executable attachments in email, now might be a good time to rethink your strategy. Because it looks like these guys won't be stopping any time soon.
