The PDF document contains numerous links to external websites, many of which are related to game cheats and hacks, such as "Free Robux" and "Coin Master" exploits. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download lure suggests an attempt to trick the user into downloading further malicious content. No scripts were extracted from this sample.
