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

The critical heuristic CVE_2010_0188 indicates exploitation of Adobe Reader's LibTIFF component via XFA forms. The CLAMAV_DETECTION heuristic further confirms this as Js.Exploit.HTML-30. The embedded URL is likely related to the XFA template. The document body contains obfuscated JavaScript that likely contributes to the exploit chain.
