MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates this PDF is malicious, specifically detecting it as 'Pdf.Exploit.Agent-36066'. The presence of embedded JavaScript, flagged by two heuristics, strongly suggests an exploit is being used to run code. The JavaScript stream is very large, indicating it may be obfuscated or contain a significant payload. Without further analysis of the script's content, the exact malicious action cannot be determined, but it is likely to download and execute a second-stage payload.
