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

The sample is a PDF file that triggers the CVE-2010-0188 exploit, targeting Adobe Reader's LibTIFF component. This exploit is known to facilitate arbitrary code execution. The embedded URL, while seemingly benign, is often used in conjunction with such exploits to fetch further malicious content. No scripts were extracted, but the exploit's nature strongly suggests a downloader or dropper functionality.
