MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button, masquerading as a game download to trick users into clicking. The primary URL, 'https://netcdn.xyz/app/479516143/minecraft-1.16-1-download-game-hack', is flagged as a malicious redirector, indicating it likely leads to a malware download. No scripts were extracted, but the presence of malicious links and the deceptive content strongly suggests a phishing or scam campaign.

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • 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
  • 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.
