The PDF contains multiple embedded links, with one critical heuristic firing indicating a malicious redirector. The primary malicious URL identified is https://ttraff.ru/pify?keyword=botany+questions+and+answers+pdf+in+tamil. The document body, though heavily obfuscated, suggests a lure related to 'Botany questions and answers pdf in tamil', likely to entice users to click the malicious link. The presence of numerous links to external PDFs, many hosted on Shopify, suggests a link farm or SEO poisoning technique to distribute the malicious content.
