MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an embedded TIFF image that exploits the CVE-2010-0188 vulnerability in Adobe Reader's LibTIFF XFA processing. This exploit allows for arbitrary code execution upon opening the document. The embedded file 'embedded_file_obj0001.bin' is likely the payload delivered by the exploit.

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
