MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF document contains embedded OLE objects, and a heuristic indicates that \objupdate forces OLE activation. This suggests the document is designed to exploit OLE vulnerabilities to execute embedded code. While no specific script content is available, the presence of OLE objects and the activation trigger strongly imply a malicious intent, likely for delivering a payload or conducting a phishing attack. The confidence is moderate due to the lack of explicit script analysis.

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
