MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains embedded URLs and a document body that explicitly mentions hacking and obtaining free items for games like Minecraft and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to download further content. No scripts were extracted from this sample, but the overall lure is consistent with social engineering tactics to trick users into downloading malware.

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.
