MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains lures for virtual currency giveaways, directing users to download a payload from the URL http://netcdn.tw/app/431946152/free-robux-giveaway-live-game-hack. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to trick users into downloading potentially harmful content. No scripts were extracted, but the document's structure and embedded URLs indicate a phishing or malware distribution attempt.
