MITRE ATT&CK
T1566.001 Spearphishing Attachment
The OLE document exhibits a large slack space and appended executable-looking payload bytes, indicating it functions as a dropper. The appended payload is likely a malicious executable, though its specific nature cannot be determined from the provided evidence. The file's SHA256 hash is included as a primary indicator.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 135,680 bytes but its declared streams total only 16,543 bytes — 119,137 bytes (88%) 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.
