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 shows signs of obfuscation, typical for malware attempting to hide its malicious actions, such as downloading and executing further payloads. The lack of readable document body text means the specific lure cannot be determined, but the technical indicators point to a classic exploit-based PDF dropper.
