MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier and embedded URI heuristics strongly indicate malicious intent, likely related to a phishing or scam campaign targeting gamers. The document body and extracted URLs suggest a lure for free in-game items or cheats for games like Roblox and Coin Master. While no scripts were explicitly extracted, the PDF structure and embedded URLs point towards a potential download or redirection to a malicious payload, aligning with a spearphishing attachment vector.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9824

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.
