MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a heuristic firing for a visual download button, suggesting a lure to download a payload. The ML classifier also flagged the PDF as malicious. The document body and extracted URLs indicate a theme of game hacks and cheats, such as for Roblox and Coin Master, which is a common social engineering tactic to entice users to click malicious links.
