The critical ClamAV heuristic 'Pdf.Exploit.Agent-6136306-0' indicates a known PDF exploit. The presence of embedded files and XFA forms are common techniques used in PDF-based exploits. While no scripts were explicitly extracted, the embedded nature and the ClamAV signature suggest the PDF is designed to exploit a vulnerability, likely leading to the download and execution of a secondary payload. The embedded URLs, though one is confirmed benign, are potential indicators of the exploit's infrastructure.

Heuristics 4

  • ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • 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.
