MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a Microsoft Word document that contains appended executable payload bytes and triggers the CVE-2006-6456 heuristic, indicating exploitation of a malformed table SPRM vulnerability. This vulnerability allows for arbitrary code execution on the victim's machine.

Heuristics 2

  • CVE-2006-6456 — Microsoft Word malformed table SPRM critical CVE exact CVE_2006_6456
    WordDocument contains a malformed table border-color SPRM in the CVE-2006-6456 shape: a valid table-SPRM cluster is followed by an invalid high-byte 0xFF SPRM where Word expects a normal sprmTBrc*Cv record. Vulnerable Word 2000/2002/2003 parsers corrupt memory while handling this malformed data structure.
  • OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOAD
    OLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
