The PDF sample contains critical heuristic firings indicating the exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader related to LibTIFF XFA images. This exploit is designed to execute arbitrary code upon opening the document. The presence of an embedded file and script payload further supports the malicious intent, likely for downloading and executing a second-stage payload. The ML classifier strongly confirms the malicious nature of the file.

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
