MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external resources, including one at http://netcdn.tw/app/406889139/haktuts-coin-master-spins-game-hack, which is likely a lure for downloading malware. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a call-to-action button further supports a malicious intent to trick users into downloading potentially harmful files. No scripts were extracted from this sample.
