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

The PDF file contains a large number of embedded links to external PDF documents, a technique often used for SEO manipulation or to distribute malicious payloads. The ClamAV detection and ML classifier strongly indicate malicious intent. The document body itself is largely garbled but contains references to the embedded URLs, reinforcing the link-farming attack pattern.
