MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an external URI pointing to a "coin-master-hack" resource, and multiple embedded URLs that appear to be related to game hacks or cheats. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of these links and the ML detection suggest a phishing or malware distribution attempt, likely initiated via a spearphishing attachment.
