MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains an XFA form and triggers the CVE-2010-0188 exploit, which is known to target Adobe Reader. The embedded JavaScript, though obfuscated, appears to be constructing strings that likely form a URL or command for downloading and executing a secondary payload. The critical ClamAV detection further confirms its malicious nature.
