MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document exhibits characteristics of an advance-fee scam, including language related to lotteries, prizes, and parcel delivery. It contains multiple embedded OLE objects, which are often used to deliver malicious payloads. While no specific script was extracted, the presence of external hyperlinks and embedded objects suggests an attempt to trick the user into interacting with malicious content or downloading further malware.
