MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URL pointing to a site offering free Minecraft downloads, a common lure for malware distribution. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple related URLs suggests a campaign to distribute potentially unwanted or malicious software. Although no scripts were directly extracted, the PDF structure and embedded URIs indicate an attempt to redirect users to external resources, likely for payload delivery.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9969

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.
