MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains heuristics indicating it is a fake invoice or payment lure, combined with a visual download button. The primary external URI points to a file hosted on 'netcdn.xyz' which is likely a malicious payload. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to trick the user into downloading potentially harmful content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9971

Heuristics 4

  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • 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.
