MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF file contains embedded JavaScript that utilizes an eval() call, a common technique for obfuscating malicious code. The ClamAV detection of 'Pdf.Exploit.Agent-36118' strongly indicates a known exploit. The script's eval() function is used to reconstruct and execute code, likely to download and execute a second-stage payload. The presence of JavaScript actions and embedded JS streams further supports this attack pattern.
