T1204 Malicious File Execution
T1027 Obfuscated Files or Information
The OLE document exhibits anomalies in its slack space and contains an appended executable-looking payload, indicating a likely attempt to hide malicious content. The heuristics suggest the file is designed to execute an unknown payload upon opening, potentially exploiting a vulnerability.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 107,008 bytes but its declared streams total only 16,486 bytes — 90,522 bytes (85%) 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.
