MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that attempts to trick the user into downloading a game hack. The ML classifier also flagged this PDF as malicious. The primary malicious URL identified is http://netcdn.tw/app/479516143/minecraft-svg-free-game-hack, which is likely the payload delivery point. No scripts were extracted, but the presence of embedded URLs and the lure text suggests a phishing or social engineering attack.
