MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains embedded URLs and a prominent link within its body text, suggesting a phishing or malware distribution attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of a download-related heuristic further supports this. The primary URL, http://netcdn.co/app/431946152/who-did-the-hackers-hack-in-roblox-game-hack, likely leads to a second-stage payload.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
