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

The PDF document contains a high-confidence ML classification indicating maliciousness and embeds a URL that appears to be a lure for game hacks. The presence of a 'download button' heuristic further supports the attack pattern of tricking the user into downloading a payload. No scripts were extracted, limiting further analysis of the payload's behavior.
