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

The RTF document contains embedded OLE objects and uses an \objupdate directive, indicating an attempt to activate embedded content. The document body explicitly instructs the user to 'click Enable editing from the yellow bar above,' which is a common lure to bypass macro security settings. This suggests the file is designed to trick the user into executing malicious code, likely for further exploitation.

Heuristics 4

  • \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
  • 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
