MITRE ATT&CK

T1204.002 Malicious File

The sample is a malicious OLE document that contains a large slack space anomaly, suggesting obfuscation or embedded malicious content. A high-severity heuristic firing indicates the use of the CreateProcess API, which is commonly used to launch external processes. This strongly suggests the document is designed to execute a payload, likely a downloader for further stages.

Heuristics 3

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 71,584 bytes but its declared streams total only 21,151 bytes — 50,433 bytes (70%) 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).
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
