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

The RTF document contains OLE object data and an \objupdate directive, indicating it is designed to activate embedded objects. The document body includes a lure instructing the user to 'enable editing', a common tactic for macro-based malware droppers. No scripts were extracted, and the specific payload or family could not be determined from the available evidence.

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
