MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous links to external websites, with a primary URL pointing to a site offering 'free coin and spin in Coin Master game hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a visual download button lure further support a malicious intent. The document likely serves as a lure to download a secondary payload or redirect to a phishing site.
