T1059.007 JavaScript
The PDF contains multiple embedded URLs, with the primary one being `https://jacksth.ru/award?keyword=concave+mirror+ray+diagram+worksheet+pdf`. ClamAV and ML classifiers indicate this PDF is malicious, likely a phishing lure disguised as a worksheet. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest it's designed to redirect users to malicious sites.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
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 https://jacksth.ru/award?keyword=concave+mirror+ray+diagram+worksheet+pdf
