T1566.001 Spearphishing Attachment
The PDF document contains a lure for "Robux Gift Card Free" and embeds a significant number of external links, many pointing to other PDF files. One of these links, http://netcdn.tw/app/431946152/robux-gift-card-free-game-hack, is flagged as a potential malicious URI. The presence of a link farm and the ML classifier's high confidence score indicate a malicious intent, likely to redirect users to a malicious download or phishing site.
