MITRE ATT&CK
T1059.001 PowerShell

The sample is a PDF file identified by ClamAV as Js.Exploit.HTML-30, indicating it contains malicious JavaScript. The presence of an XFA form further suggests a potential attack vector. The embedded URL, while seemingly benign, is part of the exploit structure. The primary attack pattern involves leveraging a PDF vulnerability to execute JavaScript, likely to download and run a secondary payload.
