The PDF contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various PDF files. One prominent URL, https://trafffi.ru/strik?utm_term=overkill+3+hack+pc, is directly embedded and suggests a malicious intent, possibly related to phishing or malware distribution. The ClamAV detection and ML classifier further 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.
