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

The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a phishing or redirection campaign. The ClamAV detection of Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports this assessment. The document body contains garbled text but also lists several of the embedded URLs, reinforcing the attack pattern.
