The PDF contains an embedded script payload, flagged by high-severity heuristics. The ML classifier also indicated maliciousness with a high score. The embedded URIs, such as http://www.gorillawalker.com/die-meistersinger-von-n-rnberg-wwv-96-chorus-score-a3154.pdf, likely serve as lures or download locations for further malicious content. The presence of an embedded script suggests an attempt to execute malicious code upon opening or interaction with the PDF.

-
Embedded script payload in PDF stream high PDF_EMBEDDED_SCRIPT_PAYLOADPDF stream bytes contain script execution markers such as ActiveXObject/CreateObject, WScript.Shell, PowerShell, or shell-exec primitives. This is stronger than ordinary PDF JavaScript because it indicates a staged external script payload hidden in stream bytes.
-
Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGEOne 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.
-
External URI info PDF_URIPDF contains an external URL action
-
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://www.gorillawalker.com/die-meistersinger-von-n-rnberg-wwv-96-chorus-score-a3154.pdf
