MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains numerous links to external resources, including one at http://netcdn.co/app/431946152/counter-roblox-hack-aimbot-2021-game-hack, which is likely a lure for downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a download button heuristic further supports a malicious intent. No scripts were extracted, but the overall structure and content point to a phishing or malware distribution attempt.
