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

The PDF document contains a lure for game cheats and hacks, specifically mentioning 'Coin Master Cheats 2021'. It embeds an external URI pointing to 'http://netcdn.co/app/406889139/coin-master-cheats-2021-game-hack', which is highly suspicious. The ML classifier also flagged this PDF as malicious with a high probability. The presence of a download button heuristic further supports the malicious intent.
