MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates a JavaScript exploit (Js.Exploit.HTML-30). The PDF contains XFA form data, which is often used to embed executable content. The embedded URL is likely part of the exploit chain. The JavaScript code appears to be obfuscated, but the overall pattern suggests it's designed to download and execute a secondary payload.
