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

The PDF file exploits CVE-2010-0188, a vulnerability in Adobe Reader's handling of XFA forms and TIFF images, to achieve code execution. The embedded JavaScript and XFA form suggest an attempt to deliver a malicious payload. The exploit targets a known vulnerability in older Adobe Reader versions, indicating a likely attempt to compromise the user's system.
