MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

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