MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI and multiple other URLs that are likely part of a lure to trick users into visiting a website for free in-game items. The ML classifier also flagged this PDF as malicious. The document body, though partially garbled, contains text related to 'Coin Master Free Spin' and the primary malicious URL, reinforcing the phishing/scam pretext.
