T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises 'script to free robux' and related game hacks. The primary external URI points to a script hosted on netcdn.tw, suggesting the PDF acts as a lure to download and execute a malicious script. The ML classifier also flagged this PDF as malicious, increasing confidence in its malicious intent.
