Malware Insights

The sample is a malicious OLE document that contains a reference to the CreateProcess API, indicating an attempt to launch an external process. The large slack space in the OLE structure is also suspicious. No document body or scripts were extracted, limiting further analysis of the specific payload or lure.

Heuristics 2

Reference to CreateProcess API high SC_STR_CREATEPROCESS

Reference to CreateProcess API
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY

OLE file is 64,928 bytes but its declared streams total only 21,151 bytes — 43,777 bytes (67%) 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).
