T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an embedded script payload and was flagged by ML classifiers and ClamAV as malicious. The presence of XFA form elements and an embedded script suggests an exploit targeting PDF reader vulnerabilities. The ClamAV detection name 'Pdf.Exploit.Agent-6136306-0' further supports this. The embedded script is likely responsible for downloading and executing a second-stage payload.
