MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for game hacks, specifically mentioning 'Coin Master Free Spins And Coins Hack'. It includes an external URI pointing to a download page for such a hack. The ML classifier also strongly indicated maliciousness. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it's designed to trick users into downloading potentially malicious software.
