T1204.001 Malicious Link
T1598.002 Host Discovery: Host Append
The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The ML classifier also flagged this PDF as malicious with high confidence. The embedded document body text, though heavily obfuscated, contains several URLs that are likely part of a link farm or redirection scheme. The primary attack pattern appears to be SEO manipulation or directing users to malicious content hosted on external sites.

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://xn--jordnraupplevelser-ptb.se/uploads/1/3/1/8/131857241/131857241.html#a+conspiracy+of+kings PDF link annotation
