MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text promoting hacks for games like Coin Master and Roblox, directing users to download applications from external sites. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests a download lure. No scripts were extracted, but the overall pattern indicates a phishing or malware distribution attempt.
