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

The sample is a PDF file that exploits the CVE-2010-0188 vulnerability in Adobe Reader, specifically targeting XFA forms. The heuristic firings indicate that the exploit payload was decoded from a raw stream within the XFA data. The embedded URL, while seemingly benign, is part of the XFA structure and could potentially be used in conjunction with the exploit. The script content, though obfuscated, suggests an attempt to load XML and execute code, consistent with exploit delivery.
