The PDF file contains a heuristic firing for a malicious redirector link. The embedded URL points to a redirector service that, when followed, leads to a URL containing 'zulfiqar ali bhutto biography pdf'. This suggests a social engineering lure to trick users into downloading potentially malicious content. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the payload.

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.
    URL https://ttraff.cc/pify?keyword=zulfiqar+ali+bhutto+biography+pdf
