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

The sample is a PDF file that exploits CVE-2010-0188, a vulnerability in Adobe Reader related to XFA forms. The ClamAV heuristic also flags it as Js.Exploit.HTML-30, indicating embedded JavaScript exploit content. The embedded URL is likely related to the exploit or a secondary payload delivery. No scripts were extracted, but the heuristics strongly suggest exploitation for client execution.
