This PDF file was flagged by a machine learning classifier and ClamAV as malicious, indicating it likely exploits a vulnerability or contains malicious content. The presence of a large number of external PDF links suggests a link farm or a method to distribute further malicious content. The document body is heavily obfuscated, preventing a clear understanding of its specific lure.

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.

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://cdn-cms.f-static.net/uploads/4365628/normal_5fe728c496df4.pdf
