T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, a common tactic for SEO spam or phishing campaigns. The heuristic PDF_SEO_LINK_FARM specifically indicates a large number of external PDF links, and the ClamAV detection as Pdf.Phishing.Trojan further supports malicious intent. The document body, though heavily obfuscated, contains a title related to human origins, likely a lure to attract clicks to the embedded URLs.

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.

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 https://lozipotod.ru/award?keyword=origen+del+hombre+americano+teorias+pdf
