MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains an embedded URL and triggers a heuristic indicating an eval() call, which is commonly used in PDF exploits. ClamAV detection of 'Pdf.Exploit.Agent-20772' further confirms its malicious nature. The presence of an eval() call suggests the execution of arbitrary code, likely to exploit a vulnerability within the PDF reader.
