The PDF contains a malicious redirector link disguised as AWS certification exam information. This link points to a URL that is known to host malicious content. The document also features a large number of external PDF links, many hosted on Shopify, which is indicative of a link farm designed to manipulate search engine results or distribute malicious content. The ML classifier strongly supports the malicious nature of this PDF.

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.
