MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains numerous links to external websites, many of which are disguised as downloadable game hacks or cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download lure further support a malicious intent. The document likely serves as a lure to download a second-stage payload.
