The PDF file contains a large number of embedded links, many of which point to a link farm designed to redirect users to malicious infrastructure. The primary URL identified, https://ttraff.ru/wb?keyword=karnataka%20b.ed%20cet%20question%20papers%20pdf, is flagged as a malicious redirector. The document body, while containing garbled text, also includes this URL and other links to PDF files hosted on various domains, suggesting a social engineering lure to disguise the malicious redirection. No scripts were extracted from this sample.
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=karnataka%20b.ed%20cet%20question%20papers%20pdf
