The PDF sample was flagged by a machine learning classifier as malicious with high confidence. Heuristics indicate the presence of an embedded script payload and an embedded file, suggesting the document is designed to exploit a vulnerability and download a second-stage payload. The embedded file 'embedded_file_obj0007.bin' is likely the malicious payload.
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
-
