MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with multiple obfuscation techniques, including string concatenation and the use of eval(). Heuristics indicate the presence of JavaScript actions and eval() calls, and ClamAV detected it as Pdf.Exploit.Agent-36118. The script's obfuscated nature and the eval() calls strongly suggest it's designed to download and execute a secondary payload, a common technique for malware delivery.
