The PDF file is identified as malicious by ML classifiers and ClamAV, exhibiting characteristics of a phishing lure. It contains an embedded URI pointing to 'https://bologen.ru/strik?utm_term=html+for+beginners+book+pdf', which is likely used to redirect the user to a malicious site. The document body is heavily obfuscated, but the presence of an image-only lure and external URIs strongly suggests a phishing or malware distribution attempt.
