T1566.001 Spearphishing Attachment

The PDF contains an embedded URL pointing to a resource promising free Robux, indicating a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. The document likely serves as a lure to download a second-stage payload.
