T1059.001 PowerShell
T1204.002 Malicious File
The PDF contains an embedded script payload, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. This script is likely designed to download and execute further malicious content. The embedded URL, http://www.gorillawalker.com/mcdougal-littell-middle-school-math-course-2-chapter-audio-summaries.pdf, is a strong indicator of the delivery mechanism. The presence of an embedded script and external URI points towards a malicious document designed for payload delivery.
Heuristics 4
-
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/mcdougal-littell-middle-school-math-course-2-chapter-audio-summaries.pdf
