MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, including one at http://netcdn.tw/app/479516143/minecraft-java-edition-code-free-game-hack, which is likely a lure for downloading malware disguised as a game hack. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple links to other game-related cheats and generators reinforces the phishing and social engineering aspect of the attack. No scripts were extracted from this sample.
