New Version of Sober Worm Spreading in Europe

A new variant of the Sober worm, Sober.F, is spreading in Europe, and some anti-virus companies are raising their threat levels for the worm due to its success. Sober.F arrives in an e-mail sent by the worm’s own SMTP engine. According to F-Secure’s description of the worm, the incoming message can have any of a large number of subject lines and message bodies, some in German and some in English. The message also contains an executable file attachment, which, according to Symantec’s analysis, contains any of a list of names with an .EXE extension and is 42,496 bytes large.
