MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent link to 'netcdn.co' disguised as a lure for free Robux, a popular in-game currency. This, combined with the ML classifier flagging the PDF as malicious, strongly suggests a phishing or scam attempt. No scripts were extracted, but the embedded URI is the primary indicator of malicious intent.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
