MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains lures for free in-game currency, specifically for Roblox, and includes an external URI pointing to a suspicious domain. The ML classifier also flagged this PDF with high confidence. The presence of a download button heuristic further supports the malicious intent of directing users to download potentially harmful content.
