T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that directs users to a page claiming to offer answers to a Cisco academy exam. This is a common phishing lure. The ML classifier and ClamAV detection strongly indicate malicious intent, likely to deliver a phishing page or further malware. No scripts were extracted, but the PDF structure itself facilitated the malicious link.

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://jumiwimov.ru/123?utm_term=cisco+academy+exam+chapter+1+answers
