MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free in-game currency, directing users to download a file from a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and multiple external URIs were extracted, indicating a likely attempt to download a second-stage payload. No scripts were extracted, but the presence of embedded URIs and the ML classification suggest a malicious intent.
