MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an embedded XFA form that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This vulnerability allows for arbitrary code execution when the document is opened. The embedded file and JavaScript actions further indicate malicious intent, likely to download and execute a secondary payload.

Heuristics 6

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
    PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
  • JavaScript action low PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • 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
  • AcroForm button with action trigger low PDF_ACROFORM_BUTTON
    PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
