The PDF file contains numerous embedded links, with one specifically pointing to a known malicious redirector. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK indicates that the link at https://ttraff.ru/pify?keyword=cards+against+humanity+print+and+play+pdf is part of a malicious infrastructure. The PDF_SEO_LINK_FARM heuristic further suggests a large number of external links are present, likely to obscure the malicious destination. The document body contains obfuscated text and references to 'wkhtmltopdf', suggesting it was programmatically generated to host these links.
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/pify?keyword=cards+against+humanity+print+and+play+pdf
