MITRE ATT&CK
T1204 User Execution: Malicious Link T1566 Phishing

The RTF file contains an OLE object and an \objupdate directive, indicating an attempt to exploit OLE object activation. The document body explicitly instructs the user to 'Enable editing' to view the content, a common social engineering lure for macro-enabled malware. No specific family could be identified, and no executable payloads or network indicators were directly extracted.

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
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
