MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs that promise free items or hacks for popular games, acting as a lure for users to download further malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates an attempt to redirect users to potentially harmful sites. While no scripts were explicitly extracted, the overall structure and embedded links suggest a downloader or phishing campaign.
