T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF 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 document body contains text related to coloring pages, which is likely a lure to disguise the malicious nature of the links. The primary purpose appears to be directing users to a network of external sites, potentially for SEO spam or to host further malicious 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://socalasta.voyagerwebsites.com/uploads/1/3/0/7/130775164/130775164.html#imagenes+de+palabras+con+g%C3%BCe+y+g%C3%BCi+para+colorear PDF link annotation
