MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscated code execution. The ClamAV detection 'Pdf.Exploit.Agent-36118' strongly suggests a known exploit. The JavaScript is heavily obfuscated, but the presence of eval() and the ClamAV signature point to a malicious exploit attempting to download and execute a secondary payload. The document body text is minimal and does not provide further context on the lure.
