MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that strongly suggest a lure for downloading game-related cheats or hacks. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.tw/app/431946152/blox-fish-free-robux-game-hack, is likely the payload delivery point. No scripts were extracted, but the presence of external URIs and the ML classification indicate a high likelihood of malicious intent.
