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 URL is likely related to the exploit's functionality. ClamAV also detected this file as Pdf.Exploit.Agent-36826, confirming its malicious nature. The script content, though obfuscated, suggests it attempts to download and execute a second-stage payload.
