MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

This PDF file contains an embedded XFA form that exploits the CVE-2010-0188 vulnerability in Adobe Reader. The embedded JavaScript attempts to download and execute a second-stage payload, indicated by the ML_NYX_PDF_MALICIOUS heuristic and ClamAV detection. The script's complex string manipulation and truncated nature prevent a full analysis of its ultimate objective, but the exploit and script execution are clear indicators of malicious intent.

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.
