MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded links and a call-to-action phrase, directing users to potentially malicious websites offering 'free' items. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple suspicious URLs indicates a likely phishing or scam attempt. No scripts were extracted, but the document structure itself facilitates the attack.
