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

The critical ClamAV heuristic indicates the presence of JavaScript exploit code within the PDF. The embedded URL, while seemingly benign, is part of the exploit structure. The XFA form heuristic further suggests a complex PDF structure often used to deliver exploits. The primary attack vector appears to be the execution of malicious JavaScript embedded within the PDF.

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.
