The PDF file contains a heuristic firing for a malicious redirector link and a link farm, indicating a likely attempt to redirect users to malicious content or engage in SEO manipulation. The document body contains text related to movie songs and metadata indicating it was generated by wkhtmltopdf, suggesting a lure document. The presence of numerous external links, including one pointing to a known malicious redirector, strongly suggests a malicious intent, possibly for phishing or malware distribution.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    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.
  • 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.
  • 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.
