MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains numerous external links, many of which point to potentially malicious domains and are part of a link farm. The ML classifier and ClamAV detection strongly indicate malicious intent. The embedded links likely serve to redirect users to phishing or malware download sites, masquerading as content related to 'horror movies in telugu dubbed free'. No scripts were extracted, but the PDF structure itself is indicative of a phishing or redirection attack.
