MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of external links, many pointing to PDF files, suggesting a link farm or SEO spam tactic. The primary URL 'https://traffnew.ru/strik?utm_term=equalizer+2+imdb' indicates a lure related to the movie 'Equalizer 2', likely to drive traffic to malicious or spam content. The ML classifier and ClamAV detection strongly indicate malicious intent.
