NEW infection W32.Sobig.F@mm

Can't Post | Private Reply

One of my emails that my ISP spam filter SpamAssassin sent to my spam file had a Virus in it. It was just discovered and it (W32.Sobig.F@mm) was the subject of the patch that Norton sent out this morning. So Norton caught it before I had a chance to be infected. But this is too close for comfort. Here is what Norton said about this spam

W32.Sobig.F@mm

Here's an e-mail that I just received from Corporate Security at MCI (where I work) regarding this virus :

A new variant of W32/Sobig, W32/Sobig.f@MM is a High Risk mass-mailing worm. It arrives as an email attachment with a .pif or .scr extension. When run, it infects the host computer, then emails itself (using its own SMTP engine) to harvested email addresses from the victim's machine. In addition, when it propagates, the worm "spoofs" the "from: field", using one of the harvested email addresses.Note: The worm copies itself onto the infected machine as: C:\WINNT\WINPPR32.EXE Caution: An infected email can come from addresses you recognize and may contain the following information:

Thanks. That's a mouthful. Hey it's been a whole day now since my Norton found a virus.

I did get another automatic update from Msft today though.
