MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs promote free in-game currency for popular games, a common lure for phishing or malware distribution. The presence of external URIs suggests the document is designed to redirect users to download further malicious content.
