T1203 Exploitation for Client Execution
T1059.007 JavaScript
The PDF file contains an XFA form that exploits CVE-2010-0188 in Adobe Reader, as indicated by multiple heuristic firings. The embedded XFA numeric stager and the ML classifier strongly suggest malicious intent. The ClamAV detection of Js.Exploit.HTML-30 further supports this, implying the XFA form likely contains JavaScript to download and execute a second-stage payload.

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.

ClamAV: Js.Exploit.HTML-30 critical CLAMAV_DETECTIONClamAV detected this file as malware: Js.Exploit.HTML-30
-
XFA numeric character-table eval stager high PDF_XFA_NUMERIC_EVAL_STAGERPDF XFA initialize script reads numeric form data from rawValue, maps the values through a short character table, and evals the reconstructed stage. This is an exploit-kit staging technique even when the final decoded layer remains encoded.
