T1204.002 Malicious File
T1059.001 PowerShell
The file is a Microsoft Word document exhibiting an OLE slack anomaly and an appended executable payload. A critical heuristic identified the CVE-2006-6456 vulnerability, indicating exploitation of a malformed table structure within the document. No VBA macros were extractable, but the presence of an appended payload suggests the document is designed to drop and execute further malicious code. The document body contains heavily corrupted text, providing no contextual clues.
Heuristics 4
-
CVE-2006-6456 — Microsoft Word malformed table SPRM critical CVE exact CVE_2006_6456WordDocument 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_ANOMALYOLE file is 173,828 bytes but its declared streams total only 94,801 bytes — 79,027 bytes (45%) 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).
-
OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOADOLE 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.
-
Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTEDolevba could not extract VBA macros (PermissionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
