MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains embedded URLs and text related to game hacks and free currency, aiming to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs indicates a likely attempt to download a second-stage payload. No scripts were extracted from this sample, but the overall pattern suggests a phishing or social engineering lure.

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.
