The PDF document contains a large number of external links, many of which are hosted on domains that appear to be part of a link farm. The document body text, though partially corrupted, includes phrases like 'New bollywood movie 2019 mkv' which serves as a lure. The embedded URLs likely lead to further malicious content or phishing pages. The heuristic 'PDF_SEO_LINK_FARM' strongly indicates a malicious intent to distribute links.

Heuristics 3

  • 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
  • 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.
