MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is a PDF file that exploits CVE-2010-0188, a vulnerability in Adobe Reader related to LibTIFF XFA image parsing. This exploit allows for arbitrary code execution on the victim's machine. The ML classifier strongly indicates maliciousness, and the embedded file heuristic suggests it may be a dropper for further payloads.

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188

PDF 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_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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
