T1059.007 JavaScript
The PDF contains numerous external links, with a critical heuristic identifying it as a link farm. One of the primary links, 'https://trafftec.ru/123?utm_term=duke+nba+players+all+time', is suspicious. Another link, 'https://s3.amazonaws.com/xanebavifamopez/lovol.pdf', is also flagged as a potential entry point for further malicious content. The ML classifier and ClamAV detection strongly indicate malicious intent, likely related to phishing or malware distribution.

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=duke+nba+players+all+time
