T1559 Component Object Model Hijacking T1027 Obfuscated Files or Information T1105 Ingress Tool Transfer

The RTF file contains an embedded OLE object, identified as a PE executable. ClamAV detected this as Win.Trojan.Prorat-23. The presence of the PE header within hex data and the OLE object class strongly suggest the file is a dropper for a malicious executable.

Heuristics 6

    Hex-encoded PE (MZ + DOS stub) found inside RTF — likely an embedded executable payload
  • ClamAV: Win.Trojan.Prorat-23 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Prorat-23
  • 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
