MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The RTF document contains OLE object data and an \objupdate directive, indicating it is designed to activate embedded objects. The document body instructs the user to 'Enable editing' and discusses financial audits, serving as a lure. The presence of OLE objects suggests the execution of embedded code, likely a macro or exploit, to achieve malicious objectives.

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
