The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.com/wix?keyword=akasam+kindiki+vaste+naa+song'. The document body, though heavily obfuscated, contains this same URL, suggesting it is the primary lure. The file was generated by wkhtmltopdf, a tool often used to create malicious PDFs. No scripts were extracted from this sample.

Heuristics 2

  • 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.
  • 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.
