The PDF file was identified as malicious by ClamAV and an ML classifier, exhibiting characteristics of a phishing or link-farming campaign. It contains numerous external URLs, including one pointing to 'maypoin.ru' with a keyword related to game cheats, suggesting a lure for potentially malicious content. The heuristic 'PDF_SEO_LINK_FARM' indicates a deliberate attempt to create a large number of links, likely for SEO manipulation or to distribute malicious payloads.

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://maypoin.ru/wix?keyword=fifa+15+coins+generator+ios+13
