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

The PDF document contains multiple embedded URLs and a call-to-action phrase, strongly suggesting a phishing or social engineering attempt. The primary URL, http://netcdn.tw/app/431946152/free-obc-roblox-game-hack, is likely intended to lead the user to download a malicious payload disguised as a game hack. The ML classifier also flagged this PDF as malicious with high confidence.
