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

The PDF file contains a large number of embedded links to other PDF files, identified by the PDF_SEO_LINK_FARM heuristic. The presence of a visual download button and the ClamAV detection as Pdf.Phishing.TtraffRobotInstall-7605656-0 strongly suggest a phishing or malicious content delivery scheme. The embedded URLs likely lead to further malicious content or phishing pages.
