MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a call-to-action lure, strongly suggesting an attempt to trick the user into downloading a secondary payload. The ML classifier also flagged this PDF as malicious with high confidence. The primary IOC is the URL http://netcdn.tw/app/431946152/free-roblox-girl-hair-not-a-model-game-hack, which is likely the download location for the malicious content.
