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

The PDF contains a prominent link to a URL that appears to offer a hack for the game "Coin Master", suggesting a social engineering lure. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a "download button" heuristic further supports the intent to trick the user into downloading a payload.
