The PDF file contains a large number of external links, a common technique for SEO poisoning or phishing campaigns. The document body, though heavily obfuscated, contains a reference to 'Chinese zodiac movie subtitle' and a URL, suggesting a lure to a malicious website. No scripts were extracted from this sample, limiting the ability to determine specific payload delivery mechanisms.

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.
