MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains numerous links to external websites, many of which are hosted on suspicious domains and offer game hacks or cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure further supports a malicious intent to trick users into downloading potentially harmful files. The primary attack vector appears to be social engineering via a phishing attachment.
