The PDF file contains a significant number of external links, identified as a link farm. The primary URL, http://skaosg.net/uploads/1/3/1/4/131410187/131410187.html#mr+banks+actor+mary+poppins+returns, is part of this farm. The ML classifier strongly indicated maliciousness. The document body text is heavily obfuscated and contains what appears to be metadata rather than user-facing content.

Heuristics 4
-
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.
-
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 http://skaosg.net/uploads/1/3/1/4/131410187/131410187.html#mr+banks+actor+mary+poppins+returns PDF link annotation
