MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests a known exploit. The extracted JavaScript file exhibits obfuscation, typical of malware attempting to hide its malicious actions. While the exact payload is not clear due to obfuscation, the presence of exploit-related heuristics and JavaScript points to a likely attack pattern involving the execution of malicious code.
