T1566.001 Spearphishing Attachment
The OLE document exhibits significant slack space and appended payload bytes, strongly suggesting it functions as a dropper. The heuristics indicate the presence of an executable payload appended to the OLE structure. While no document body or script content is available for further analysis, the appended payload is the primary indicator of malicious intent.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 203,776 bytes but its declared streams total only 16,486 bytes — 187,290 bytes (92%) 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.
