T1204.002 Malicious Link
The PDF contains numerous embedded links pointing to a network of domains, indicating a link farm or SEO poisoning tactic. The primary heuristic 'PDF_SEO_LINK_FARM' confirms the presence of 30 external PDF links, with 'chanako.com' being a dominant host. The ML classifier also strongly flagged this PDF as malicious. The document body text, though partially garbled, includes a URL that matches one of the extracted links, suggesting a deliberate attempt to direct users to external 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://yinghuangwangshangyule.br3h.com/uploads/1/3/0/5/130542769/130542769.html#cual+es+la+formula+de+la+longitud+dela+circunferencia PDF link annotation
