The PDF contains numerous embedded links, with a critical heuristic identifying a redirector link to 'ttraff.ru' and a link farm heuristic pointing to multiple PDF hosting domains. The document body, though heavily obfuscated, contains the target URL, suggesting a lure to download further content or navigate to malicious sites. The presence of these link farms and redirectors indicates a campaign focused on SEO poisoning or traffic redirection to malicious infrastructure.
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=pediatric%20liver%20transplantation%20pdf
