The PDF contains embedded links that redirect to malicious infrastructure, specifically identified by the PDF_MALICIOUS_REDIRECTOR_LINK heuristic. The PDF_SEO_LINK_FARM heuristic indicates a large number of outbound links, many hosted on cdn.shopify.com, suggesting an attempt to manipulate search engine results or distribute content through a seemingly benign platform. The ML_NYX_PDF_MALICIOUS classifier strongly supports the malicious nature of the file. The primary malicious IOC is the redirector URL.

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.
