Malware Insights
The PDF file contains a significant number of embedded links, with a heuristic identifying a PDF link farm and another flagging a malicious redirector. The document body, though partially corrupted, contains text related to a safety data sheet and includes the malicious URL. The primary malicious URL, https://ttraff.ru/pify?keyword=calcium+hypochlorite+safety+data+sheet+uk, is likely used to redirect the user to a secondary malicious site. The presence of numerous links, many hosted on Shopify, suggests an attempt to disguise malicious activity within a large volume of seemingly benign content.
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=calcium+hypochlorite+safety+data+sheet+uk
