The PDF file contains a significant number of embedded links, with a critical heuristic firing for a PDF link to known malicious redirector infrastructure.

The primary malicious URL identified is https://ttraff.ru/wb?keyword=learning%20of%20ms%20excel%20pdf, which is likely used for redirection. The presence of a large PDF link farm on Shopify domains, alongside other unknown URLs, indicates a coordinated effort to distribute malicious content or engage in SEO manipulation for malicious purposes.
