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 also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lures strongly indicate an attempt to trick users into downloading malware.
