MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body contains multiple URLs, including one pointing to 'netcdn.co', which are presented as 'hacks' for games like Roblox and Coin Master. This suggests a social engineering lure to trick users into downloading malware. No scripts were extracted, but the presence of external URIs and the ML classification indicate a high likelihood of malicious intent.

  • 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.
