MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.004 Command and Scripting Interpreter: PowerShell

The sample is a PDF document identified as malicious by ClamAV. Static analysis detected the use of XFA forms and specifically flagged the CVE-2010-0188 exploit targeting Adobe Reader's LibTIFF component. The embedded URL, while seemingly benign, is part of the exploit chain. The exploit likely leads to the execution of a secondary payload.
