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 redirection scheme, commonly used to distribute malware or conduct phishing attacks. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious traffic generation intent. No scripts were extracted, and the document body was heavily obfuscated and truncated, preventing a more detailed analysis of the specific lure.

Heuristics 3
