This PDF file contains a large number of external links, many pointing to other PDF documents hosted on various platforms. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, suggesting a tactic to manipulate search engine results or distribute further malicious content. The presence of a ClamAV detection for 'Pdf.Phishing.Trojan' and a high ML score further support its malicious nature. The primary IOC is the initial URL which likely serves as an entry point to this link farm.

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://laborke.ru/pbw?utm_term=chemical+elements+names+and+symbols
