This PDF file was flagged as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. The PDF contains a large number of external links, with one prominent link pointing to 'https://trafftec.ru/123?utm_term=political+science+101+book+pdf+in+hindi', suggesting a link farm or phishing lure. The presence of multiple external PDF links further supports the idea of a malicious link farm designed to distribute further malicious content or lead users to phishing sites.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
