MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file contains an embedded script payload, indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic. This script is likely designed to download and execute a secondary malicious file, as suggested by the 'Suspicious extracted artifact' heuristic which flags a long encoded blob and an embedded file. The presence of an embedded file further supports the attack pattern of delivering a malicious payload.

Machine Learning

  • Nyx PDF Classifier malicious score 1.0000

Heuristics 5

  • Suspicious extracted artifact high 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
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Embedded script payload in PDF stream info 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 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.
