T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of embedded external links, identified as a link farm, suggesting an attempt to manipulate search engine results or redirect users to potentially malicious sites. The ML classifier strongly indicated maliciousness, and the presence of numerous PDF_URI firings supports this. While no scripts were directly extracted, the structure and link farm heuristic point towards a malicious document designed for redirection.

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://datanetguatemala.com/uploads/1/3/2/6/132682930/132682930.html#zumba+exercise+songs PDF link annotation
