MITRE ATT&CK
T1204.002 Malicious File

The file is a malicious OLE document detected as Win.Trojan.Agent-584354 by ClamAV. It contains an embedded OLE object (ole10native_00.bin) and references to APIs like VirtualAlloc, LoadLibrary, and GetProcAddress, indicating it likely attempts to load and execute a secondary payload. The presence of the CVE-2026-21514 heuristic further suggests exploitation of an OLE vulnerability.
