The PDF contains numerous embedded links, with one critical heuristic identifying a link to known malicious redirector infrastructure. The document body, though partially corrupted, contains text related to academic papers and the malicious URL, suggesting a lure to trick users into clicking the link. The ML classifier strongly supports the malicious verdict. The primary attack vector appears to be a link farm designed to redirect users 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.com/pify?keyword=bihar+board+12th+model+paper+2020+science+pdf
