T1203 Exploitation for Client Execution
T1059.007 JavaScript
The PDF sample exploits CVE-2010-0188, a known vulnerability in Adobe Reader's handling of XFA forms, to achieve code execution. The ML classifier strongly indicates maliciousness. The embedded script payload suggests the PDF is designed to download and execute a secondary stage, though the script itself is heavily obfuscated and truncated.

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188PDF contains the CVE-2010-0188 exploit template: XFA JavaScript heap-spray setup, a generated TIFF image payload, and assignment of that TIFF data to an XFA image field rawValue to trigger Adobe Reader's LibTIFF parser.
-
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF 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 file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
