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

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which strongly suggests a malicious intent to redirect users. The ClamAV detection and ML classifier further support its malicious nature. The document body, though partially obfuscated, also contains many of these URLs, reinforcing the link farm attack pattern.
