MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for a "Coin Master Hack" and includes multiple URLs pointing to download sites. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest the document is designed to trick users into downloading and executing a secondary payload.
