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

The PDF document was flagged by an ML classifier as malicious with a high probability. It contains multiple embedded URLs, including one pointing to 'netcdn.tw', which are likely intended to direct users to download malicious content disguised as game hacks. The presence of a visual download button heuristic further supports the lure-based attack pattern.
