MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs related to game hacks and cheats. The presence of an external URI pointing to 'netcdn.co' suggests an attempt to download a secondary payload or redirect the user to a malicious site. While no scripts were explicitly extracted, the PDF structure and embedded URLs are consistent with a phishing or malware distribution lure.

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.
