The PDF contains a mass of external links, many of which are hosted on Shopify, but one critical link points to a known malicious redirector. The document body text, though garbled, suggests a lure related to 'Chrome extension development tutorial pdf'. The heuristic firings indicate the PDF is a malicious redirector and part of a link farm, designed to trick users into installing something by pretending to be a tutorial. The primary malicious IOC is the redirector URL.
Heuristics 4

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.
-
