Detection & IOCsextracted from sources · hover to see the quote

  • Trigger vector is a crafted Excel file containing a malformed record object; inspect Excel files for anomalous or malformed record objects as the exploit delivery mechanism.
  • File-based delivery via Excel documents should be treated as the primary attack surface; any Excel file from an untrusted source should be treated with suspicion, particularly those exploiting record parsing in legacy formats.
  • ·Vulnerability affects a wide range of Microsoft Office versions including Office 2000 SP3, Office XP SP3, Office 2003 SP3, Office 2004 and 2008 for Mac, 2007 Microsoft Office System SP1 and SP2, Open XML File Format Converter for Mac, Excel Viewer 2003 SP3, Excel Viewer, and Compatibility Pack SP1 and SP2 — detection/patching scope must cover all these variants.
