MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of embedded links to other PDF files hosted on various domains, indicating a link farm designed to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and malicious distribution intent. The document body itself is heavily obfuscated and appears to contain fragments of URLs, but the primary attack vector is the link farm.
