MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs, including one pointing to 'netcdn.co' which is associated with downloading an application. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a call-to-action button suggests a phishing or malware distribution attempt. No scripts were extracted from this sample, but the overall structure and content indicate a lure for downloading potentially unwanted or malicious software.

Machine Learning

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.
