The PDF file contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.ru/wix?keyword=medical+certificate+format+pdf+rajasthan'. This URL is likely used to redirect users to a malicious site. The document also contains a large number of external PDF links, a common SEO spam technique to improve search engine ranking for malicious content. The ML classifier strongly indicates maliciousness.

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.
