MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a link to known malicious infrastructure, disguised as a download for game cheats. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the heuristic firings strongly suggest a malicious redirector intended to download a second-stage payload.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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
  • 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.
