MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links and a visual call-to-action button, strongly suggesting an attempt to trick the user into downloading a secondary payload. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of external URLs and the lure indicate a phishing or scam attempt, likely related to game hacks or cheats.
