MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links, identified as a link farm, and is flagged as an advance-fee scam lure. The primary purpose appears to be directing users to external sites, likely for phishing or malware distribution, under the guise of a prize or delivery notification. No scripts were extracted, but the structure strongly suggests a malicious intent to redirect users.
