MITRE ATT&CK
T1204.002 Malicious File

The critical ClamAV heuristic 'Pdf.Exploit.Dropped-78' indicates this PDF is designed to exploit a vulnerability and drop malware. The presence of an XFA form and an embedded URL further supports this. The embedded URL is likely used to download the secondary payload.

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 exited 1. 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.
