MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The sample is a PDF file identified as malicious by multiple heuristics, including a critical detection for CVE-2010-0188, which exploits a vulnerability in Adobe Reader's LibTIFF component. The embedded XFA script contains JavaScript that is likely responsible for executing the exploit. The script's content is heavily obfuscated and truncated, but the presence of the exploit and embedded script strongly suggests an attempt to compromise the user's system.

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.
