Malware Insights
The PDF file was identified as malicious due to the presence of a large number of embedded links. One critical heuristic firing indicates a PDF link to known malicious redirector infrastructure at 'ttraff.ru'. Another critical heuristic firing flags the document as a PDF SEO link farm, with numerous links pointing to Shopify domains, including 'cdn.shopify.com/s/files/1/0429/9502/4033/files/anatoly_t_fomenko.pdf'. The document body contains garbled text but also includes the suspicious URL and several Shopify URLs, reinforcing the link farm observation. The primary intent appears to be SEO manipulation or distribution of further malicious content via the link farm.
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/wix?keyword=sto+phaser+sets
