MITRE ATT&CK
T1204.002 Malicious File: User Execution T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains embedded XFA (XML Forms Architecture) data, which is leveraged by the CVE-2010-0188 exploit targeting Adobe Reader. ClamAV also detected this as Js.Exploit.HTML-30, indicating JavaScript-based exploitation. The embedded URL is likely related to the XFA template, but the primary attack vector is the exploit itself.
