This PDF file was identified as malicious by multiple heuristics, including ClamAV and an ML classifier. It contains a large number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. One of the embedded URLs, 'https://trafftec.ru/123?utm_term=brookland+cayce+high+school+phone+number', is particularly suspicious and likely part of the malicious infrastructure.

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://trafftec.ru/123?utm_term=brookland+cayce+high+school+phone+number
