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

The PDF contains multiple embedded URLs and a prominent external URI pointing to a suspicious domain, likely intended to trick users into downloading malware disguised as a game. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a 'download button' heuristic further supports the lure-based attack pattern.
