MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a lure for Coin Master free spins and hacks, directing users to a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of an embedded URI further supports a malicious intent. No scripts were extracted, but the document body and heuristics indicate a phishing attempt to redirect users to a potentially harmful site.
