MITRE ATT&CK
T1559.001 Component Object Model Hijacking T1027 Obfuscated Files or Information

The RTF document contains an embedded OLE object which itself contains a PE executable header. ClamAV signatures confirm this is Win.Trojan.Clicker-3800. The presence of the PE header within the RTF object data indicates the document is designed to deliver and execute a secondary payload.

Heuristics 7

  • 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
  • ClamAV: Win.Trojan.Clicker-3800 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Clicker-3800
  • ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
    ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
  • 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.
