MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with an eval() call, strongly indicating an attempt to execute malicious code. ClamAV identifies this as Pdf.Exploit.Agent-13266. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, which is a common attack pattern for PDF exploits. The document body was not readable, so the rationale is based on the script and heuristic findings.
