MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains multiple embedded URLs pointing to sites offering free Robux, a common lure for distributing malware. 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 overall pattern suggests a phishing or malware distribution attempt.
