MITRE ATT&CK
T1204 User Execution T1204.002 Malicious File

The RTF document contains OLE object data and an \objupdate directive, indicating it is designed to activate embedded objects. The document body provides a lure, instructing the user to 'click Enable editing from the yellow bar above', a common tactic for macro-based malware delivery. The heuristics suggest the file is intended to bypass Office macro security settings.

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
