MITRE ATT&CK
T1059.001 PowerShell

The file is a PDF document that contains embedded URLs pointing to external PDF files. The ClamAV detection 'Pdf.Dropper.Agent-7126981-0' and the ML classifier strongly indicate malicious intent. The primary attack pattern observed is the use of embedded links to trick users into downloading further malicious content. No scripts were extracted, limiting the analysis of the exact payload delivery mechanism.
