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

The PDF file contains a large number of embedded links pointing to external PDF files hosted on various domains. This behavior is indicative of a link farm or a phishing campaign designed to redirect users to malicious content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the malicious intent. No scripts were extracted from this sample.
