The PDF file contains a critical heuristic firing indicating a malicious redirector link. The embedded URL, 'https://ttraff.cc/pify?keyword=air+pollution+project+book+in+marathi+pdf+download', is the primary indicator of malicious intent. This suggests the document is designed to trick users into visiting a harmful site, likely for phishing or malware distribution.

Heuristics 2

    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.
