MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document body and extracted URLs indicate a lure for free in-game currency (Robux, Coin Master spins) by directing users to external websites. The ML classifier strongly flagged this PDF as malicious, suggesting it likely leads to a scam or a further stage of infection. Although no scripts were explicitly extracted, the PDF structure and embedded URIs are indicative of a malicious document designed to trick users into visiting malicious sites.

Machine Learning

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.
