MITRE ATT&CK
T1059.001 PowerShell
The OLE document exhibits anomalies with a large slack region and an appended executable-looking payload, indicating the presence of hidden malicious code. While VBA macros could not be extracted due to an unsupported format, the embedded URL heuristic suggests a delivery mechanism. The appended payload strongly suggests the file is designed to download and execute a second-stage payload.
Heuristics 3
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 117,248 bytes but its declared streams total only 16,543 bytes — 100,705 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.
-
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.
