MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs, with the primary one being http://netcdn.tw/app/406889139/coin-drop-master-free-game-hack, suggesting a lure for users to download a file. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent. Although no scripts were explicitly extracted, the PDF structure and embedded URLs indicate a likely attempt to deliver a second-stage payload.
