MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains embedded URLs that redirect to potentially malicious content, masquerading as game hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious workflow. The document body, though partially obfuscated, contains references to game cheats and download links, indicating an attempt to trick the user into downloading a 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.
