MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external resources, including one at http://netcdn.co/app/406889139/coin-master-daily-free-spin-app-game-hack, which is likely a lure for downloading a malicious application. The ML classifier also flagged this PDF with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest an attempt to trick users into downloading potentially harmful software.
