MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an external URI pointing to a suspicious URL, and the ML classifier strongly flagged it as malicious. The document body, though heavily obfuscated, contains references to Roblox and game-related terms, suggesting a lure for free items or cheats. The presence of multiple embedded URLs further supports the malicious intent to redirect users to potentially harmful content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9941

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.
