Threat Advisory: McAfee AVERT raises risk assessment to medium for consumers on new W32/SOBER.P@MM virus

<p>New Sober Worm Tries to Prey on World Cup Fans</p>
<p>SYDNEY, May 3, 2005 — McAfee, Inc., the leader in Intrusion Prevention and Risk Management solutions, today announced that McAfee AVERT (Anti-virus and Vulnerability Emergency Response Team), the world-class research division of McAfee, Inc., raised the risk assessment to Medium on the recently discovered W32/Sober.p@MM, also known as Sober.p. Sober.p is a prolific worm that spreads via email, sending itself to addresses found on the victim’s machine. The worm arrives as a .zip file attached to e-mail and has many of the same functionalities as its W32/Sober.k@MM predecessor. The worm was first reported to McAfee AVERT researchers this morning PST and to date McAfee AVERT has received more than 60 reports of the virus in the wild from unique senders.</p>
<p>Threat Overview
Sober.p is a mass mailing threat that contains its own SMTP engine to construct outgoing messages, which are written in German or English. It harvests addresses from local files and then uses the harvested addresses to send itself. This produces a message with a spoofed From address. The attachment comes in the form of a .zip file that contains an executable file inside, named “winzipped-text_data.txt .pif”. The filename contains a dual extension with the first extension being .TXT, followed by many spaces and the second extension .PIF. When the ZIP archive is extracted and the contained PIF file is manually executed, the virus may display a fake error message.</p>
<p>Users would need to manually extract the executable from the .zip file and manually run the attachment in order to be infected.</p>
<p>The virus constructs messages in either German or English using random characteristics.</p>
<p>German Version:</p>
<p>From: (address is spoofed)
Subject: WM-Ticket-Auslosung</p>
<p>Message Body: The message body will be one of the following:</p>
