MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a malicious redirector link and a visual download button, suggesting a lure for users to obtain free in-game items. The ML classifier also flagged this PDF with high confidence. The embedded URLs likely lead to further malicious content or phishing pages, and the document body contains obfuscated text and URLs related to game cheats and hacks.

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.
