MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains an embedded XFA form that triggers the CVE-2010-0188 vulnerability in Adobe Reader. This exploit is designed to allow for arbitrary code execution. The embedded file, 'embedded_file_obj0001.bin', is highly suspicious and likely contains the secondary payload. The document body is heavily obfuscated and does not provide clear user-facing text, but the exploit and embedded artifact strongly suggest a malicious intent to compromise the user's system.

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
