T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, many of which are SEO-optimized and point to other PDF files, suggesting a link farm or phishing operation. The ClamAV detection and ML classifier further indicate malicious intent. While no scripts were extracted, the presence of numerous external URLs and the heuristic firings strongly suggest this document is designed to redirect users to malicious or phishing sites.
