T1204.002 User Execution: Malicious File
The PDF document contains a fake CAPTCHA lure, aiming to trick users into clicking a link for 'Free Robux'.

While no scripts were explicitly extracted, the presence of a fake CAPTCHA and external links strongly indicates an attempt to lead the user to a malicious download or phishing page.
