The PDF file was identified as malicious due to a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it points to known malicious infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic fired, revealing a large number of embedded external links, many hosted on Shopify. The primary malicious URL identified is https://ttraff.ru/pify?keyword=tecnica+septoplastia+pdf, which is likely used to redirect users to a phishing or malware-hosting site. The document body contains garbled text but includes the malicious URL and several other Shopify-hosted PDF 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.
