T1204.002 Malicious File T1059.001 PowerShell

The PDF sample was flagged by multiple heuristics, including a critical ClamAV detection for Pdf.Dropper.Agent-7326243-0 and an ML classifier indicating maliciousness. It contains an embedded script payload and an embedded file, suggesting it's designed to deliver a secondary malicious payload. The embedded URL is highly suspicious and likely serves as the download location for this payload.

Heuristics 6

  • ClamAV: Pdf.Dropper.Agent-7326243-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Dropper.Agent-7326243-0
  • 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
  • Suspicious extracted artifact info 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 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.
