MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous links to external websites, including one at http://netcdn.tw/app/406889139/coin-master-spin-hack-2021-game-hack, which is likely a lure for downloading a malicious application. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a visual download button heuristic further support this assessment. The document's content and associated URLs suggest a scam aimed at tricking users into downloading game cheats or hacks.
