MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that mimic links to game-related cheats and rewards, such as 'Coin Master Links Free Spins'. The presence of an external URI heuristic firing on 'http://netcdn.co/app/406889139/coin-master-links-free-spins-game-hack' strongly suggests this is a downloader or a lure for further malicious activity. The ML classifier also flagged this PDF as highly suspicious.
