The PDF contains a link to a known malicious redirector, ttraff.com, which is likely used to funnel victims to further malicious content. The document body, though heavily corrupted, contains the same URL and references a PDF related to grammar exercises, suggesting a lure. The presence of numerous other PDF links, many hosted on cdn.shopify.com, indicates a link farm strategy to improve SEO and distribute malicious 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.
-
