MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The ML classifier strongly indicated maliciousness, and the document body contains a URL associated with game hacks and cheats. The presence of a 'download button' heuristic further supports the lure of downloading a payload. The primary URL http://netcdn.co/app/431946152/free-communism-shirt-roblox-game-hack is likely the intended download destination for a malicious application.

  • 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.
