MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises free in-game currency and hacks for popular games, strongly suggesting a phishing or scam lure. The ML classifier also flagged this PDF as malicious with high confidence. The primary IOC is the URL http://netcdn.tw/app/431946152/free-robux-discord-game-hack, which likely hosts the malicious payload.
