The RTF document contains OLE object data and uses an \objupdate directive, indicating an attempt to exploit OLE object activation for code execution. This is a common technique for delivering malicious payloads via spearphishing attachments. No specific family could be identified due to the lack of further indicators.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE

  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
