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

The PDF file contains a large number of embedded external links, a technique commonly used for SEO poisoning or phishing campaigns. The heuristic 'PDF_SEO_LINK_FARM' specifically identifies this behavior, pointing to a network of linked PDF files hosted on various domains. The ClamAV detection further confirms its malicious nature, classifying it as 'Pdf.Phishing.TtraffRobotInstall'. The embedded links likely lead to malicious content or further stages of an attack.
