T1204.002 Malicious File T1566.001 Spearphishing Attachment T1204 User Execution

The PDF file contains XFA (XML Forms Architecture) data, which is often used to embed exploits. Static analysis identified a critical heuristic match for CVE-2010-0188, an Adobe Reader vulnerability related to LibTIFF processing within XFA forms. This indicates the file is designed to exploit this specific vulnerability upon opening in a vulnerable version of Adobe Reader, likely leading to the download and execution of a secondary payload. The embedded URL, while seemingly benign, is part of the XFA structure and could be involved in 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.
