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

The RTF document contains embedded OLE object data and uses an \objupdate directive, indicating an attempt to activate embedded content. The document body includes a lure instructing the user to 'enable editing', a common tactic for macro-based malware delivery. While no scripts were extracted, the heuristics suggest the file is designed to exploit user interaction to execute malicious code, likely through the embedded OLE object.

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
