MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is an OLE document exhibiting a large slack space anomaly, indicating potential obfuscation or embedded malicious content. Heuristics firing for LoadLibrary and GetProcAddress strongly suggest the file is designed to execute arbitrary code, likely through an exploit.

Heuristics 3

Reference to LoadLibrary API high SC_STR_LOADLIBRARY

Reference to LoadLibrary API
Reference to GetProcAddress API high SC_STR_GETPROCADDRESS

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

OLE file is 106,560 bytes but its declared streams total only 8,934 bytes — 97,626 bytes (92%) 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).
