T1566.001 Spearphishing Attachment

The PDF file contains a large number of external links, many of which point to other PDF files, suggesting a link farm or redirection mechanism. The primary URL, 'https://synerhu.ru/pbw?utm_term=most+accurate+yes+or+no+tarot', is likely used to lure victims with a fake tarot reading service. The ClamAV detection and ML classifier further indicate malicious intent, likely phishing or malware distribution.
