MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are related to obtaining free in-game currency or cheats for popular games. The primary external URL, http://netcdn.tw/app/431946152/roblox-how-to-get-free-clothes-game-hack, is likely a lure to download a malicious payload. The ML classifier also flagged this PDF as malicious with high confidence. No scripts were extracted, but the presence of external links and the lure of free in-game items strongly suggest a phishing or malware distribution attempt.
