The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. The document body contains fragments of text and URLs, including 'http://babcafe.net/uploads/1/3/1/0/131071082/131071082.html#a+todos+los+chicos+de+los+que+me+ena' and 'http://iducknetwork.com/uploads/1/3/0/7/130776056/4677045.pdf'. This suggests a link farm or SEO poisoning attack, potentially leading users to malicious content or phishing pages.

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.
