MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious File T1059.001 Command and Scripting Interpreter: PowerShell

The sample is a PDF document that exploits CVE-2010-0188, a vulnerability in Adobe Reader related to XFA forms. The embedded script payload within the XFA form is likely responsible for executing malicious code. The presence of embedded files and XFA scripts indicates a sophisticated attack designed to leverage known vulnerabilities for initial compromise.

Heuristics 6

  • 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.
  • XFA form contains executable script high CVE related PDF_XFA_SCRIPT
    PDF embeds an XFA form whose dataset contains a <script> or <xfa:script> block — XFA scripting has been the exploit primitive for several Adobe Reader RCEs (CVE-2010-0188 family, CVE-2018-4901, and others). Plain XFA without scripts is far less risky.
  • 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
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
