The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/wb?keyword=pronunciation%20reading%20exercises%20pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, including one to 'https://cdn.shopify.com/s/files/1/0433/4888/5662/files/gulorovezoti.pdf'. The document body, though heavily obfuscated, contains these URLs, suggesting a lure to trick users into clicking through to malicious content.
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.
-
Embedded URL info EMBEDDED_URLOne 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.URL https://ttraff.ru/wb?keyword=pronunciation%20reading%20exercises%20pdf
