T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains a mass of external links, many of which are SEO-optimized and point to download sites for games and free in-game currency. The primary URL, 'https://netcdn.xyz/app/479516143/minecraft-pc-download-free-full-version-game-hack', suggests a lure for downloading software. The ML classifier also strongly indicated maliciousness.

  • 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.
