MITRE ATT&CK

T1059.003 Command and Scripting Interpreter: Windows Command Shell

The sample is a malicious OLE document with a high slack anomaly, indicating potential obfuscation or embedded malicious content. A high-severity heuristic firing for CreateProcess API suggests the document attempts to launch an external process. No document body or script content was available for further analysis, limiting the ability to determine the specific payload or delivery mechanism.

OLE file is 67,232 bytes but its declared streams total only 21,151 bytes — 46,081 bytes (69%) 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).
