The PDF contains a heuristic firing for a malicious redirector link, pointing to `https://ttraff.ru/pify?keyword=design+e+comunica%25C3%25A7%25C3%25A3o+visual+bruno+munari+pdf+download`. This URL is likely used to redirect users to a malicious site. Additionally, the PDF exhibits characteristics of a link farm, with numerous embedded URLs, many of which are hosted on `cdn.shopify.com` and other file-sharing domains, suggesting an attempt to obscure the final malicious destination. The ML classifier also strongly flagged this PDF as malicious.
