MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded URLs and text that lure the user into clicking a link for 'free Robux'. The presence of a visual download button and the ML classifier flagging the PDF as malicious strongly suggest a phishing or scam attempt. The primary IOC is the malicious URL embedded within the document, which likely leads to a credential harvesting or malware distribution site.
