What is W32.Sobig and how does it affect me? For those of you being hit by the Sobig-F worm, you can easily defend your GroupWise servers using GWGuardian. If you do not currently own GWGuardian+AV, you can download a fully functional trial copy at http://www.messagingarchitects.com/gwguardianee.
The Sobig worm has made an unwelcome return in the form of its latest variant, W32/Sobig-F. The mass-mailing, network-aware worm can spread via email and network shares. W32/Sobig-F attempts to spread by copying itself to Windows network shares and uses the Network Time Protocol to one of several servers in order to determine the current date and time.
What action can I take from here?
If you are running GroupWise 5.5, 6.0, 6.5 or even Notes, Exchange and Netmail GWGuardian will prevent Sobig-F from even reaching your mail server.
GWGuardian also includes many more features including 8 levels of anti-spam & anti-virus protection. Find out why so many enterprises and government organizations chose GWGuardian and to download a trial version, please visit us at http://www.messagingarchitects.com/gwguardianee.
