T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, many of which point to other PDFs, indicating a link farm designed to host malicious content or phish users. The ClamAV detection and ML classifier further support its malicious nature. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest it's designed to redirect users to potentially harmful content.
