MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a call-to-action phrase, strongly suggesting a lure for users to click through to potentially malicious websites. The ML classifier also flagged this PDF as malicious. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-link-2021-april-game-hack, appears to be a lure for in-game currency.
