MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one at http://netcdn.tw/app/406889139/free-spins-for-coin-master-ios-game-hack, which likely serves as a lure for downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a call-to-action button further supports a phishing or malware distribution attempt. No scripts were extracted, but the overall structure and embedded URLs suggest a phishing or downloader attack.
