MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that promote 'free spins' and 'free robux', suggesting a lure for users to download a payload. The ML classifier strongly flagged this PDF as malicious. The primary IOC is the external URI pointing to a download link, likely serving as the initial stage of a download and execution attack.
