MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF file contains embedded XFA (XML Forms Architecture) content, which is known to be a vector for exploits. Specifically, the 'CVE_2010_0188' heuristic indicates exploitation of a vulnerability in Adobe Reader related to LibTIFF and XFA. The embedded JavaScript, though obfuscated, is designed to execute and likely download a second-stage payload, as suggested by the 'ML_NYX_PDF_MALICIOUS' and 'CLAMAV_DETECTION' firings. The benign URL found is likely a red herring or part of the XFA template structure.

XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
Embedded script payload in PDF stream low PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
