MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a lure for free Roblox items, directing users to a URL that likely hosts a malicious application. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and embedded URLs supports a phishing or social engineering attack pattern. No scripts were extracted from this sample, but the overall structure and content indicate a malicious intent to trick users into downloading a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 3

  • 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.
