MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, with a primary focus on luring users to download applications promising free in-game currency for popular games. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the document's structure and embedded links suggest a phishing or social engineering attack.
