MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The RTF document contains OLE object data and an \objupdate directive, indicating it's designed to activate embedded objects. The document body includes a lure instructing the user to 'click Enable editing from the yellow bar above,' a common tactic for macro-based malware delivery. The presence of these elements suggests the file is a malicious dropper, though the specific payload and family could not be determined from the provided 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
