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

The PDF file contains embedded scripts and triggers an 'eval()' call, indicating malicious JavaScript execution. The ML classifier strongly flags this PDF as malicious. The embedded scripts are likely designed to download and execute a second-stage payload, although the exact mechanism is obscured by obfuscation. The presence of XFA forms and embedded files further supports a malicious intent.

  • Nyx PDF Classifier malicious score 0.9963

Heuristics 6

  • eval() call high PDF_EVAL
    eval() found — commonly used for obfuscated exploit execution
  • Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD
    PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
  • 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
  • ClamAV scan did not complete on extracted artifact info CLAMAV_SCAN_INCOMPLETE
    ClamAV did not complete on 3 carved artifact(s); EXTRACTED_FILE_CLAMAV may be missing for this run. The result is not cached so a later submission will retry the scan.
  • 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.
