MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an XFA form and utilizes the ASCII85Decode filter, which are indicators of malicious intent. Crucially, a critical heuristic identified the CVE-2010-0188 exploit targeting Adobe Reader's LibTIFF component, indicating the file is designed to achieve arbitrary code execution. The exploit is embedded within an XFA image payload.

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.
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85
    ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
