T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting it is part of a link farm or SEO manipulation scheme. The document body, though partially corrupted, contains text related to 'Poemas cortos de amor para jovenes' and references wkhtmltopdf, indicating a deceptive lure. The primary attack pattern involves redirecting users to a network of external websites, likely for malicious advertising or to host further malicious content.

-
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://74-123-79-231.mgwnet.com/uploads/1/3/0/7/130775871/130775871.html#poemas+cortos+de+amor+para+jovenes PDF link annotation
