MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF file contains embedded XFA (XML Forms Architecture) data, which is known to be a vector for exploits. Heuristics and ClamAV detection confirm the presence of an exploit targeting CVE-2010-0188, specifically within the XFA form. The embedded JavaScript, though heavily obfuscated, likely contributes to the exploitation process by preparing or delivering the payload. The primary attack vector is the exploitation of a client-side vulnerability.

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.
