MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent call-to-action button and an embedded URL pointing to a "robux-store-free-game-hack". The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of it being used to deliver a second-stage payload or lead users to a phishing site. The presence of multiple related URLs further supports the malicious intent.
