The RTF document contains embedded OLE object data and utilizes the \objupdate directive, which is a strong indicator of an attempt to automatically execute embedded content upon opening. This technique is commonly used to deliver secondary payloads. No specific family could be identified from the available heuristics.

Heuristics 3

  • \objupdate forces OLE activation high RTF_OBJUPDATE
    RTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
