MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.co', which are likely intended to lead users to download malicious content or exploit kits related to game hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a download button lure further support a malicious intent. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.
