MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF document contains an embedded XFA form with a payload targeting CVE-2010-0188, a known vulnerability in Adobe Reader's LibTIFF processing. This indicates the document is designed to exploit this vulnerability upon opening, leading to arbitrary code execution. No scripts were extracted, and the document body was unreadable, but the critical heuristic firing strongly suggests exploitation.

Heuristics 4

  • 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.
  • 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
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
