MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.co', which are designed to trick users into downloading game hacks and cheats. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of a malicious payload being delivered via these links. While no scripts were explicitly extracted, the presence of external URIs and the ML detection suggest an attempt to facilitate the download of a second-stage payload.
