MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one at 'http://netcdn.tw/app/431946152/how-to-get-a-free-skin-noob-roblox-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 from this sample, but the overall structure and embedded URLs suggest a phishing or malware distribution attempt.
