MITRE ATT&CK
T1204.002 Malicious File: User Execution

The PDF file contains XFA form elements, which are leveraged by the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader's handling of XFA forms, specifically related to LibTIFF processing. The heuristic firings and ClamAV detection strongly indicate that this PDF is designed to execute arbitrary code upon opening in a vulnerable reader. The embedded URL, while not directly malicious in reputation, is associated with XFA templates and is likely part of the exploit chain.

Heuristics 5

  • 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.Agent-36821 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-36821
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED
    The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSEOF. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
