MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains an embedded URI pointing to a suspicious URL, and a machine learning classifier flagged it as malicious. The document body text, while appearing to offer free Roblox coloring pages, also contains the same suspicious URL, suggesting a lure to download potentially unwanted or malicious content. 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.
