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

The PDF document contains a prominent link to 'netcdn.tw' which is associated with downloading a 'coin-master-hack-mod-apk'. This, combined with the ML classifier flagging the PDF as malicious and the presence of a download button heuristic, strongly suggests a lure to download potentially unwanted or malicious software. The document body and embedded URLs reinforce this theme of game hacks and cheats.
