The PDF contains a large number of external links, many pointing to Shopify domains, but one critical link redirects to a known malicious domain (ttraff.cc). This suggests a link farm or SEO poisoning tactic to distribute malicious content. The document body, though heavily obfuscated, contains the malicious URL, indicating an attempt to lure users to a harmful site. The ML classifier strongly flagged this PDF as malicious.

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.
