MITRE ATT&CK
T1059.003 Windows Command Shell T1059.001 PowerShell

The PDF is encrypted and contains embedded files, suggesting it is a container for malicious content. A high-severity heuristic indicates the document explicitly lures the user to execute commands via the clipboard, likely to download and run further payloads. The document body is unreadable, but the heuristic is sufficient to infer the attack pattern.

Machine Learning

  • Nyx PDF Classifier clean score 0.0085

Heuristics 5

  • Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LURE
    Document tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context
  • Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • Encrypted PDF (string and stream contents are opaque to static scan) info PDF_ENCRYPTED
    PDF declares /Encrypt — string objects and stream contents are encrypted with the standard security handler (RC4 or AES). On its own this is informational; legitimate encrypted documents include signed contracts, billing statements, and rights-managed material. Static heuristics cannot inspect encrypted payload bytes.
  • 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.
    URL http://www.iec.ch In PDF document text

Extracted artifacts 18
