MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action, strongly suggesting a lure to download a secondary payload. The primary URL, https://netcdn.online/app/406889139/coin-master-free-coins-and-spins-game-hack, is presented as a way to obtain free game resources, a common social engineering tactic. The ML classifier's high confidence score further supports the malicious nature of this file.
