MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs promote methods to earn Robux, a virtual currency, which is a common lure for phishing and malware distribution. The presence of external URIs suggests an attempt to redirect the user to a malicious site or download a payload.
