MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.007 JavaScript

The sample is identified as malicious by multiple heuristics, including a critical finding for CVE-2010-0188, which indicates an exploit targeting Adobe Reader's XFA form processing. The ML classifier also strongly flagged the PDF as malicious. The embedded script, although obfuscated, likely contains JavaScript that is executed by the exploit, leading to the download or execution of a secondary payload.

  • ClamAV: Pdf.Exploit.Agent-36821 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-36821
  • 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.
