T1203 Exploitation for Client Execution
T1059.004 Command and Scripting Interpreter: PowerShell
The sample is a PDF file that leverages the XFA (XML Forms Architecture) feature to exploit CVE-2010-0188, a vulnerability in Adobe Reader's handling of LibTIFF images within XFA forms. The XFA numeric character-table evaluation stager is used to trigger the exploit, which is designed to execute arbitrary code. The embedded URL is likely related to the XFA template, but its direct maliciousness is not confirmed by the heuristics.

-
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.

-
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.
