T1204 Malicious Link
T1204.002 Malicious Link: Malicious File
The PDF sample was flagged by a machine learning classifier with high confidence as malicious. Heuristics indicate the presence of an embedded script payload and an embedded file, suggesting an attempt to exploit a PDF vulnerability. The embedded URLs, while mostly benign or unknown, are part of the document's structure. The ML classifier's high score and the embedded script payload strongly indicate a malicious intent to deliver further stages.
Machine Learning
- Nyx PDF Classifier malicious score 1.0000
Heuristics 4
-
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF 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_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
Embedded URL info EMBEDDED_URLOne 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://ns.adobe.com/xdp/
