T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous embedded links to external websites, many of which appear to be part of a link farm designed to obscure malicious activity. The document body, though corrupted, contains text suggesting a financial tool lure, which is likely a pretext to drive users to these malicious URLs. The ML classifier strongly indicates malicious intent.

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://meshayla.com/uploads/1/3/0/7/130776518/130776518.html#planilla+excel+para+calcular+van+y+tir
