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

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.co', which are likely intended to lure users into downloading malicious files disguised as game cheats or codes. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent. No scripts were extracted from this sample.
