MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded JavaScript and external URIs, strongly suggesting malicious intent. The document body and extracted URLs promote 'free Robux' and game hacks, indicating a lure for users to download potentially harmful files. The ML classifier's high confidence score further supports the malicious nature of this PDF, likely delivered as a spearphishing attachment.

Heuristics 4

  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • 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.
