MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1027 Obfuscated Files or Information
The OLE document exhibits a large slack space and an appended executable payload, indicating it's designed to deliver a secondary malicious component. The presence of appended executable bytes strongly suggests a dropper functionality, likely delivered via spearphishing.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 87,296 bytes but its declared streams total only 12,338 bytes — 74,958 bytes (86%) 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.
