MITRE ATT&CK
T1559.001 Component Object Model Hijacking T1204.002 Malicious File

The RTF document contains an embedded OLE object, identified as a package object. Further analysis reveals a PE header within the object's data, indicating it is likely a malicious executable. The presence of these indicators strongly suggests the RTF is a dropper for a secondary payload.

Heuristics 4

  • PE header (with DOS stub) in hex data critical RTF_MZ_HEX
    Hex-encoded PE (MZ + DOS stub) found inside RTF — likely an embedded executable payload
  • Package object class high RTF_OBJCLASS_PACKAGE
    OLE Package object — can wrap arbitrary files
  • 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
