MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains numerous external links, many of which are disguised as book downloads, a common lure for phishing or malware distribution. The ClamAV detection and ML classifier indicate malicious intent. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest it's designed to redirect users to malicious sites.
