MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for downloading "Minecraft 1.16 Apk Download" and embeds multiple URLs pointing to other PDF files, many of which are related to game cheats and free in-game currency. The ML classifier flagged this PDF as malicious with high confidence. The presence of external URIs and the overall theme suggest a phishing or malware distribution attempt, likely via spearphishing attachment.
