T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/pify?keyword=icao+annex_14_aerodromes_volume_1_pdf'. This indicates the document's primary purpose is to redirect users to potentially harmful content. The presence of a large number of external PDF links, while many are benign Shopify links, suggests a link farm or SEO manipulation tactic to obscure the malicious redirector. The ML classifier also strongly flagged this PDF as malicious.
