MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that promotes downloading a 'hack' for Coin Master, indicating a lure for potentially unwanted or malicious software. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs suggests an attempt to redirect the user to a download site.
