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

The RTF document contains embedded OLE objects and uses lures to trick the user into enabling content, which is a common technique for malware droppers. The document body discusses internal controls and auditor opinions, a likely pretext to disguise the malicious intent. No specific IOCs like URLs or hashes were extracted from the embedded objects.

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
