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

The PDF file contains a large number of embedded URLs pointing to external PDF files across various domains. This "link farm" technique is commonly used to obscure malicious destinations or to distribute phishing content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports a phishing or traffic redirection intent. No scripts were extracted from this sample.

Heuristics 3
