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

The PDF document contains multiple embedded URLs that lead to resources advertising game hacks and cheats. The presence of a 'download button' heuristic and the ML classifier's high confidence score suggest a malicious intent to trick users into downloading potentially harmful files. The document body, though heavily obfuscated, contains references to 'Coin Master Hack' and a URL that aligns with the overall theme.
