Heuristics 4
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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://ttraff.ru/pify?keyword=%25D1%2580%25D1%2583%25D0%25BA%25D0%25BE%25D0%25B2%25D0%25BE%25D0%25B4%25D1%2581%25D1%2582%25D0%25B2%25D0%25BE+%25D0%25B1%25D0%25BE%25D1%2580%25D1%2582%25D0%25BF%25D1%2580%25D0%25BE%25D0%25B2%25D0%25BE%25D0%25B4%25D0%25BD%25D0%25B8%25D0%25BA%25D0%25B0+%25D0%25B0%25D1%258D%25D1%2580%25D0%25BE%25D1%2584%25D0%25BB%25D0%25BE%25D1%2582
