MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by ClamAV and an ML classifier. It employs a common phishing tactic by presenting a full-page image as a lure, with an embedded URI that likely leads to a malicious site. The PDF's structure and the presence of an external URI strongly suggest it's designed to redirect users to a potentially harmful destination.
