MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.tw', which are likely intended to lure users into downloading malware disguised as game hacks or cheats. The ML classifier strongly flagged this PDF as malicious, supporting the assessment that it is part of a phishing or social engineering campaign. No scripts were extracted, but the presence of external URIs and the ML detection indicate a high likelihood of malicious intent.
