MITRE ATT&CK
T1566.001 Spearphishing Attachment
The file is an OLE document with a significant amount of appended executable-looking payload bytes, indicating it's likely a dropper or loader. The OLE slack anomaly and appended payload heuristics strongly suggest malicious intent. No VBA macros were extractable, but the appended payload is the primary indicator of compromise.
Heuristics 3
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 79,872 bytes but its declared streams total only 16,543 bytes — 63,329 bytes (79%) 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.
-
Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTEDolevba could not extract VBA macros (PermissionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
