MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File T1027 Obfuscated Files or Information

The RTF document contains an embedded OLE object, identified as a package object. This object contains a PE header in hex data, indicating an embedded executable. The DOC BODY excerpt reveals the embedded object is named 'CLICK HERE.exe' and appears to be located at 'C:\DOCUMENT~1\Baloon\0016~1\CLICKH~1.EXE'. This suggests the document is designed to trick the user into opening an executable file disguised as a clickable link, likely leading to malware execution.

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.
