MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains a critical heuristic indicating the presence of an exploit for CVE-2010-0188, which targets Adobe Reader's LibTIFF component. This exploit is embedded within an XFA form and is designed to execute arbitrary code. The embedded file, 'embedded_file_obj0001.bin', is likely the secondary payload. The attack pattern is therefore focused on exploiting this known vulnerability to achieve initial code execution.

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.
