Malware Insights
The PDF file contains a large number of embedded links, many of which point to external resources, a technique often used for SEO poisoning or to redirect users to malicious sites. The primary heuristic firing indicates a malicious redirector link, specifically 'https://ttraff.ru/pify?keyword=caracteristicas+sociales+del+adulto+joven+pdf', which is designed to lure users into clicking through to potentially harmful content. The document body, though heavily obfuscated, contains references to the same malicious URL and a large list of Shopify-hosted PDF files, suggesting a coordinated effort to distribute malicious 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=caracteristicas+sociales+del+adulto+joven+pdf
