MITRE ATT&CK
T1559.001 Component Object Model Hijacking

The RTF document contains embedded OLE object data, specifically identified as a package object class and containing a PE header in hex data. This strongly suggests the document is a container for a malicious executable. The extracted artifact 'objdata_00_off000000ce.bin' is the likely payload. No scripts were extracted from this sample.

Heuristics 5

  • 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
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
