The PDF file was identified as malicious due to a critical heuristic firing for a PDF redirector link pointing to 'https://ttraff.ru/pify?keyword=agony+review+game+informer'. Additionally, a PDF link farm heuristic indicated the presence of numerous external links, with 'https://cdn.shopify.com/s/files/1/0434/8972/2534/files/human_skeleton_anatomy_activity_answer.pdf' being the first identified. The document body contains obfuscated text and embedded URLs, further supporting the malicious intent of directing users to potentially harmful sites.

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.
