Malware Insights
The PDF file contains numerous embedded links, a technique often used in SEO link farms to artificially boost search engine rankings or distribute malicious content. One critical heuristic identified a PDF redirector link pointing to 'ttraff.cc', which is known malicious infrastructure. The document body, though heavily obfuscated, contains the same redirector URL and a benign-looking Shopify URL, suggesting a lure to a malicious site. No scripts were extracted, but the primary attack pattern involves redirecting users through a chain of links, ultimately leading to a malicious destination.
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.cc/pify?keyword=ortopedia+pediatrica+staheli+pdf+descargar
