T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious Attachment

The PDF file was flagged by a machine learning classifier and ClamAV as malicious, specifically identifying it as Pdf.Exploit.Agent-6136306-0. The presence of an embedded script payload within a PDF stream, combined with XFA form usage, indicates an attempt to exploit vulnerabilities. The embedded script is likely responsible for downloading and executing a second-stage payload.
