MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a document body that mimics a guide for in-game currency, likely to trick users into clicking malicious links. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates a potential download or redirection attempt. No scripts were extracted, but the overall structure suggests a phishing or malware distribution lure.
