MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains numerous embedded URLs, including one pointing to 'netcdn.co' which is flagged as a malicious external URI. The document body, though heavily obfuscated, contains references to game cheats and hacks, suggesting a lure for users to download potentially unwanted or malicious software. The ML classifier also strongly indicated maliciousness.
