T1059.001 PowerShell

The PDF file contains a large number of embedded links to external PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content. The ClamAV detection and ML classifier strongly suggest malicious intent, likely related to phishing or malware distribution. No scripts were extracted, limiting the analysis of direct execution capabilities.
