Malicious Office (OLE) — malware analysis report

Heuristics 2

• OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
  OLE file is 446,526 bytes but its declared streams total only 12,338 bytes — 434,188 bytes (97%) 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_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.
