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

The RTF file contains embedded OLE objects that are automatically linked and updated, indicating an attempt to execute code upon opening. The document body includes a lure instructing the user to 'enable editing', a common tactic for macro-based malware droppers to bypass security measures. The presence of these elements strongly suggests a malicious intent to deliver a payload.

Heuristics 4

  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • \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
