http://www.microsoft.com/technet/security/advisory/968272.mspx

Many versions of Excel are vulnerable, including 2000, 2002, 2003, 2007, 2004/2008 for Mac, Excel Viewer/Excel Viewer 2003.


A trojan exploiting an unpatched Microsoft Excel vulnerability has been reported from the field. McAfee Avert Labs has confirmed that Microsoft Excel 2007 and 2003 are affected. Other versions may also be impacted.

McAfee DAT files identify known malicious Excel spreadsheet files as Exploit-MSExcel.r trojan, and dropped files as BackDoor-DUE trojan in the 5534 DATs.

As with the initial Exploit-PDF.i threat, current attacks are very targeted and limited. When succesfull, it installs a backdoor that attempts to connect a remote site port 80 and waits for commands.
