The RTF document contains embedded OLE objects, and the \objupdate heuristic indicates that these objects are likely activated upon opening. This suggests the document is designed to exploit vulnerabilities or trick the user into executing embedded content, potentially leading to a second-stage payload download and execution. 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.
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
  • Embedded OLE object medium RTF_OBJEMB
    RTF contains \objemb — embedded OLE object
