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

The critical ClamAV heuristic indicates the presence of JavaScript exploit code within the PDF. The embedded URL, while seemingly benign, is often used in conjunction with exploit code. The XFA form heuristic further suggests a complex PDF structure that could be used to hide malicious content. The JavaScript likely attempts to download and execute a second-stage payload, as indicated by the 'Js.Exploit.HTML-30' detection.
