The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/pify?keyword=english+synonyms+words+pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous external links, including one to 'https://cdn.shopify.com/s/files/1/0434/2883/9581/files/zejufuto.pdf'. The document body, though heavily obfuscated, contains references to the redirector URL and the topic 'English synonyms words pdf', suggesting a lure to a malicious site.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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.
