The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.com/wix?keyword=%25C3%25A9valuation+lecture+compr%25C3%25A9hension+ce2+p%25C3%25A9riode+5'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, many hosted on Shopify. The document body, though heavily obfuscated, contains the same malicious URL and appears to be a lure related to educational content. The ML classifier also strongly flagged this PDF as malicious.
