MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The sample is a PDF file detected by ClamAV as Js.Exploit.HTML-30, indicating it contains malicious JavaScript. The presence of an XFA form further suggests an exploit is likely. The embedded URL, while seemingly benign, is part of the exploit structure. The JavaScript is likely used to download and execute a second-stage payload.
