These emails suggest to recipients that their Internet use has been monitored by the FBI or CIA and that they have accessed illegal Web sites. The email directs users to open the ZIP attachment containing the executable, which once opened delivers the Sober virus payload. It then spreads by searching the infected computer for other email addresses to send copies of itself to, but ignoring any domains for certain security organizations, including MessageLabs.
The virus will send emails in German for domains ending .DE or .AT and a few others, with the remainder being sent in English. It seems that despite warnings, many recipients are still opening the emails allowing the virus to spread still further.
Also, since yesterday, MessageLabs has stopped three new variants of W32/Mytob, one of which was W32/Mytob.ED!ee4e, for which we have stopped over 10,000 copies.
MessageLabs stopped all copies destined for clients using the MessageLabs Anti-virus service.
