MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an embedded XFA form that triggers the CVE-2010-0188 exploit in Adobe Reader. This exploit is designed to execute arbitrary code, and ClamAV detection confirms the presence of the Pdf.Exploit.CVE_2010_0188-10 variant. The embedded file 'embedded_file_obj0008.bin' is likely the delivered payload.

Heuristics 6

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
    PDF contains the CVE-2010-0188 exploit template: XFA JavaScript heap-spray setup, a generated TIFF image payload, and assignment of that TIFF data to an XFA image field rawValue to trigger Adobe Reader's LibTIFF parser.
  • ClamAV: Pdf.Exploit.CVE_2010_0188-10 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.CVE_2010_0188-10
  • Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD
    PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
  • 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.
