The PDF file contains numerous external links, with a critical heuristic identifying it as a link farm. The primary URL, 'https://traffking.ru/strik?utm_term=traffic+engineering+and+transport+pl', suggests a lure related to traffic engineering. The presence of many external PDF links, including one to 'datirelegewewat.weebly.com', indicates a potential distribution or phishing campaign. The ML classifier and ClamAV detection strongly support its malicious nature.

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://traffking.ru/strik?utm_term=traffic+engineering+and+transport+pl
