The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.cc'. This URL is likely used to funnel users to a malicious site. Additionally, the PDF includes a large number of external links, many hosted on Shopify, which is flagged as a link farm. The document body contains garbled text but includes the suspicious URL, reinforcing the malicious intent. The ML classifier also strongly indicated maliciousness.
