MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1027 Obfuscated Files or Information
T1105 Ingress Tool Transfer
The OLE document exhibits a large slack region and an appended executable-looking payload, strongly suggesting it is a malicious dropper. While VBA macros could not be extracted due to an unsupported format, the presence of appended payload bytes indicates the file's intent is to deliver and execute additional malicious code. The SHA256 hash is included as a primary identifier.
Heuristics 3
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 920,596 bytes but its declared streams total only 20,632 bytes — 899,964 bytes (98%) 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.
