MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF sample exploits CVE-2010-0188, a vulnerability in Adobe Reader related to XFA forms and LibTIFF processing. This exploit allows for arbitrary code execution. An embedded file was also detected, suggesting a downloader or dropper functionality. The specific exploit and embedded artifact point to a malicious PDF designed to compromise the user's system.

Heuristics 5

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
