MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a Microsoft Word document that triggers a critical heuristic for CVE-2006-6456, indicating exploitation of a malformed table SPRM vulnerability. The large slack space in the OLE structure also suggests potential obfuscation or embedded malicious content. The document body contains heavily garbled text, which is typical of obfuscated malicious documents, and several embedded URLs were extracted, though none were definitively malicious.

Heuristics 3

  • 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 document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 344,576 bytes but its declared streams total only 94,801 bytes — 249,775 bytes (72%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
