MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, suggesting a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the document body text explicitly mentions free items for games like Roblox and Coin Master, directing users to a suspicious URL. No scripts were extracted from this sample, but the presence of external URIs and the high ML score indicate a likely attempt to redirect users to a malicious site.

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.
