MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF sample contains embedded JavaScript within an XFA form, which is leveraged by the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader's handling of TIFF images within XFA forms to achieve code execution. The embedded script is heavily obfuscated but appears to be designed to download and execute a second-stage payload.

ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
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.
