MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous URLs and a prominent link to 'netcdn.co' which is likely a lure for downloading a malicious payload disguised as game cheats. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it's designed to trick users into downloading and executing further malware.
