The file is a PDF document that contains embedded XFA (XML Forms Architecture) data. Heuristics indicate a critical vulnerability, CVE-2010-0188, related to LibTIFF and XFA exploitation. This suggests the PDF is designed to exploit a flaw in Adobe Reader to achieve code execution. The embedded URL is likely related to the XFA template, but its reputation is unknown.

Heuristics 5

  • 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.
