MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an XFA form, which is a known vector for exploiting vulnerabilities. ClamAV detected it as Js.Exploit.HTML-30, indicating embedded JavaScript is likely used for exploitation. The embedded URL, while seemingly benign, is part of the exploit chain. The JavaScript is responsible for downloading and executing a second-stage payload.

Heuristics 4

  • ClamAV: Js.Exploit.HTML-30 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Js.Exploit.HTML-30
  • 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.
