The PDF document contains a link to a known malicious redirector, disguised as a download for "Minecraft 1.15 2 Hacks". The ML classifier also flagged this PDF as malicious with high confidence. The presence of a visual download button further supports the lure. The document likely serves as a dropper or redirects to a site hosting further malicious content.
