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

The PDF file contains a large number of embedded links to external PDF documents hosted on various domains. This behavior is indicative of a link farm or a phishing lure, aiming to redirect users to potentially malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing classification. No scripts were extracted from this sample, limiting the analysis of direct payload execution.
