T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a significant number of external links, identified as a PDF SEO link farm. The primary lure appears to be a link to a Spanish-language article about ancient American civilizations, which in turn leads to a collection of other PDF files hosted on various domains. This suggests a tactic to drive traffic to potentially malicious or ad-filled websites, or to distribute further malware payloads disguised as documents.

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://74-123-77-115.mgwnet.com/uploads/1/3/0/7/130739492/130739492.html#cuales+son+las+principales+civilizaciones+de+la+antiguedad+en+america PDF link annotation
