T1566.001 Spearphishing Attachment
The OLE document exhibits anomalies in its structure, specifically a large slack region and appended executable-looking payload bytes. This suggests the file is designed to deliver a secondary malicious payload. No specific family could be identified from the available evidence.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 113,152 bytes but its declared streams total only 16,536 bytes — 96,616 bytes (85%) 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.
