MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, many of which are related to game cheats and free in-game currency, suggesting a lure for users to download potentially malicious files. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a suspicious nature. No scripts were extracted from this sample, but the overall pattern indicates a phishing or social engineering attempt to drive downloads.
