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

The PDF file contains a large number of embedded links to external PDF files hosted on various domains, indicating a link farm or redirection scheme. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. No scripts were extracted from this sample, and the document body contained mostly garbled text, making it difficult to ascertain the exact lure.
