MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The file is a PDF document identified by ClamAV as Pdf.Exploit.Dropped-78, indicating it's a known exploit dropper. The presence of an embedded URL, although seemingly benign, is often used in conjunction with exploit code within PDF files to download secondary payloads. The XFA form detected suggests a complex structure often leveraged for exploitation.

Heuristics 4

  • ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Dropped-78
  • 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.
