The PDF contains numerous external links, with a critical heuristic identifying a link farm. One prominent URL, 'https://soxebez.ru/award?keyword=hospital+and+clinical+pharmacy+by+pratibha+nand+pdf', and another from the link farm, 'http://zexawil.22web.org/fepabu.pdf', are likely used to redirect users to malicious sites. ClamAV detection and ML classification further support its malicious nature, indicating a phishing or malware distribution scheme.
