MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious, and it contains an external URI pointing to a suspicious download link. The document body, though heavily obfuscated, contains references to 'Coin Master Apk Hack' and a URL that appears to be a lure for downloading an application. While no scripts were explicitly extracted, the presence of embedded URLs and the ML classification suggest an attempt to trick the user into downloading a second-stage payload.

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.
